* Add tests to ensure we can marshal and unmarshal our min/max times
Related to https://github.com/prometheus/client_golang/issues/614
Instead of implementing all the time parsing, we can special-case handle
these 2 times. This means if times in this format show up that
time.Parse can't handle they will still error, but we can marshal/parse
our own min/max time

Currently, When `/etc/mime.types` has a unusual mime type, web of prometheus uses the type and you may get unexpected result.
With this change, web returns consistent Content-Type header for static js and css files
To reproduce:
1. Add a type at the end of `/etc/mime` like `text/x-js js`
2. Run prometheus
3. Request js file like `http://localhost:9090/static/vendor/js/jquery.min.js`
4. You will see Content-Type of the response is `text/x-js` instead of `application/javascript`

github.com/gogo/protobuf => v1.2.1
google.golang.org/grpc => v1.19.1
github.com/grpc-ecosystem/grpc-gateway => v1.18.5
It also replaces github.com/cockroachdb/cmux by github.com/soheilhy/cmux

This change switches the remote_write API to use the TSDB WAL. This should reduce memory usage and prevent sample loss when the remote end point is down.
We use the new LiveReader from TSDB to tail WAL segments. Logic for finding the tracking segment is included in this PR. The WAL is tailed once for each remote_write endpoint specified. Reading from the segment is based on a ticker rather than relying on fsnotify write events, which were found to be complicated and unreliable in early prototypes.
Enqueuing a sample for sending via remote_write can now block, to provide back pressure. Queues are still required to acheive parallelism and batching. We have updated the queue config based on new defaults for queue capacity and pending samples values - much smaller values are now possible. The remote_write resharding code has been updated to prevent deadlocks, and extra tests have been added for these cases.
As part of this change, we attempt to guarantee that samples are not lost; however this initial version doesn't guarantee this across Prometheus restarts or non-retryable errors from the remote end (eg 400s).
This changes also includes the following optimisations:
- only marshal the proto request once, not once per retry
- maintain a single copy of the labels for given series to reduce GC pressure
Other minor tweaks:
- only reshard if we've also successfully sent recently
- add pending samples, latest sent timestamp, WAL events processed metrics

This is fixed by explicitly checking for `null` and returning the string

The scrape manage receiver's channel now just saves the target sets
and another backgorund runner updates the scrape loops every 5 seconds.
This is so that the scrape manager doesn't block the receiving channel
when it does the long background reloading of the scrape loops.
Active and dropped targets are now saved in each scrape pool instead of
the scrape manager. This is mainly to avoid races when getting the
targets via the web api.
When reloading the scrape loops now happens in parallel to speed up the
final disared state and this also speeds up the prometheus's shutting
down.
Also updated some funcs signatures in the web package for consistency.

When prom2 came out the storage querier interface consolidated to a
single Select() method. While doing this it makes it impossible as the
implementer of the querier to know if you are being called for metadata
or actual data. The workaround has been to check if the SelectParams are
nil, which the federation call is always nil. This has 2 negative
consequences (1) remote implementations interpret this as a metadata
call, which makes the federation endpoint return nothing. (2) this means
that the storage implementations don't get the same information passed
down to them as far as SelectParams goes.
This diff simply adds SelectParams to the Select() call in the
federation handler

Fix race by properly locking access to scrape pools. Use separate mutex for information needed by UI so that UI isn't blocked when targets are being updated.
* web: replace deprecated InstrumentHandler()
This change replaces the deprecated InstrumentHandler function by the
equivalent functions from the promhttp package.
The following metrics are removed:
* http_request_duration_microseconds (Summary).
* http_request_size_bytes (Summary).
* http_requests_total (Counter).
And the following metrics are added instead:
* prometheus_http_request_duration_seconds (Histogram).
* prometheus_http_response_size_bytes (Histogram).
* promhttp_metric_handler_requests_in_flight (Gauge).
* promhttp_metric_handler_requests_total (Counter).
* Update github.com/prometheus/common/route package
* web: refactor using the new prometheus/common/route package
After removing the checkbox in #3913 the only remaining element that
looked like it was the new Show Annotations checkbox on the Alerts page.
Which in turn didn't look like the Enable query history checkout on the
graph page. So:
1. This takes the Enable query history button as canonical.
2. Updates the show annotations button code to match it.
3. Simplifies the JS for the checkbox.
The new Service Discovery page uses the CSS/JS from the Targets page but
used slightly differently. This makes the job header match in the
Service Discovery page for a more consistent look-n-feel.
* Added only healthy to Targets
This adds a "Only heathly" button to supplement the "Only unhealthy"
button. The two are mutually exclusive.
I've also added a red/green text color to the buttons.
Arguably this could be a toggle instead if folks think this is
worthwhile... Happy to modify it.
* Moved functions above init
* Simplifed code and made prettier
* Appeased codeacy
* Made buttons square
* Fix JS error: cannot read source of undefined
When the page was refreshed with queries on the page,
the updateTypeaheadMetricsSet function was called before
the typeahead had been initialized.
* Fix: updates URL when query submits
When queries were submitted by pressing enter, the URL did not update
to reflect the change. Not sure why, but this was only the case when
the queries were non-simple, meaning when either labels werre specified
or other promql functions were used.
* Rebase master and make assets
This is a very minor UX change. The current "No Alert rules" present
table row has the `alert_header` class attached. This changes the cursor
and some other stuff and makes sense with the populated table but less
sense with the unpopulated table. So removing it the latter case.
This adds a parameter to the storage selection interface which allows
query engine(s) to pass information about the operations surrounding a
data selection.
This can for example be used by remote storage backends to infer the
correct downsampling aggregates that need to be provided.
When you have no alerting rules defined you get a screen sharing this
information in the WebUI. If no rules are defined then you instead see
an empty white screen. This adds a "No rules" defined `else` clause and
a `Rules` header to the page.
* Do not autoselect the first item in the dropdown
* Historical queries only show in dropdown when toggled on
* Move shared behavior to queryHistory.isEnabled function
* Do not auto submit selected history queries
net.Listener converts 0.0.0.0 to :: which fails for hosts where IPv6 is
disabled. This change uses the original listen address parameter instead
of grpcl.Addr().String().
Federation makes use of dedupedSeriesSet to merge SeriesSets for every
query into one output stream. If many match[] arguments are provided,
many dedupedSeriesSet objects will get chained. This has the downside of
causing a potential O(n*k) running time, where n is the number of series
and k the number of match[] arguments.
In the mean time, the storage package provides a mergeSeriesSet that
accomplishes the same with an O(n*log(k)) running time by making use of
a binary heap. Let's just get rid of dedupedSeriesSet and change all
existing callers to use mergeSeriesSet.
When there is an empty result set, the Prometheus server replies with
{"status":"success","data":{"resultType":"vector","result":null}}
That "null" reply was not handled correctly by the graphing library.
This commit handles that case and shows "no data" in the UI console view
instead of throwing an error in the browser javascript console.
Fixes#3515
