Fabian Reinartz 7ccd4b39b8 *: implement query params
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.

This is currently getting lost, this will soon be in a metric and we
don't want it dropping to 0 on every reload.

beorn7 c2e9a151ab Make all rule links link to the "Console" tab rather than "Graph"
Clicking on a rule, either the name or the expression, opens the rule
result (or the corresponding expression, repsectively) in the
expression browser. This should by default happen in the console tab,
as, more often than not, displaying it in the graph tab runs into a
timeout.

Brian Brazil cc867dae60 Copy previous series and alert state more intelligently.
Usually rules don't more around, and if they do it's likely
that rules/alerts with the same name stay in the same order.

If rules/alerts with the same name are added/removed this
could cause a blip for one cycle, but this is unavoidable
without requiring rule and alert names to be unique - which we don't
want to do.

Matt Bostock 926a5ab3dd rules/manager.go: Fix race between reload and stop
On one relatively large Prometheus instance (1.7M series), I noticed
that upgrades were frequently resulting in Prometheus undergoing crash
recovery on start-up.

On closer examination, I found that Prometheus was panicking on
shutdown.

It seems that our configuration management (or misconfiguration thereof)
is reloading Prometheus then immediately restarting it, which I suspect
is causing this race:

Julius Volz c187308366 storage: Contextify storage interfaces.
This is based on https://github.com/prometheus/prometheus/pull/1997.

This adds contexts to the relevant Storage methods and already passes
PromQL's new per-query context into the storage's query methods.
The immediate motivation supporting multi-tenancy in Frankenstein, but
this could also be used by Prometheus's normal local storage to support
cancellations and timeouts at some point.

Julius Volz ed5a0f0abe promql: Allow per-query contexts.
For Weaveworks' Frankenstein, we need to support multitenancy. In
Frankenstein, we initially solved this without modifying the promql
package at all: we constructed a new promql.Engine for every
query and injected a storage implementation into that engine which would
be primed to only collect data for a given user.

This is problematic to upstream, however. Prometheus assumes that there
is only one engine: the query concurrency gate is part of the engine,
and the engine contains one central cancellable context to shut down all
queries. Also, creating a new engine for every query seems like overkill.

Thus, we want to be able to pass per-query contexts into a single engine.

This change gets rid of the promql.Engine's built-in base context and
allows passing in a per-query context instead. Central cancellation of
all queries is still possible by deriving all passed-in contexts from
one central one, but this is now the responsibility of the caller. The
central query context is now created in main() and passed into the
relevant components (web handler / API, rule manager).

In a next step, the per-query context would have to be passed to the
storage implementation, so that the storage can implement multi-tenancy
or other features based on the contextual information.
