One of our users today asked us if dashes were allowed in recording rule names.
We asserted that they were not, but also that we could not remember for certain.
After determining empirically that they are _not_ allowed, I realized that the
documentation could be slightly clearer about valid rule names.
This PR simply adds a note to the documentation re-iterating that the rules must
be valid metric names - and more importantly, adds a link to where a user can
read what those *are*, in case they were not aware (or did not know where to find it).

This adds support for a new query param on the new `api/v1/metadata`
endpoint that provides metadata for a specified metric via the V1 API.
It collapses metadata that is equal across all targets, and aggregates
under the same metric name the ones that differ.

* api: provide per metric metadata
This adds a new endpoint that provides per metric metadata via the V1 API.
It collapses metadata that is equal across all targets, and aggregates under the same metric name the ones that differ.
* Allow tests to be asserted on response length
Some tests e.g. limit on API responses, don't require an assertion on
equality.
This allows us to assert against response length instead of
equality.

The desired shards calculation now properly keeps track of the rate of
pending samples, and uses the previously unused integralAccumulator to
adjust for missing information in the desired shards calculation.
Also, configure more capacity for each shard. The default 10 capacity
causes shards to block on each other while
sending remote requests. Default to a 500 sample capacity and explain in
the documentation that having more capacity will help throughput.

Previously, the wording could be misunderstood as setting honor_labels
to "false" for federation.
This also adds scraping the Pushgateway as a typical use case for
honor_labels=true.

Document the behavior of an empty `ec2_sd_config` `region` setting. If this is
omitted or blank, the region is discovered from the instance metadata, if available.
If it is blank and instance region metadata is not available, an error will
result ("EC2 SD configuration requires a region").

With v0.16.0 Alertmanager introduced a new API (v2). This patch adds a
configuration option for Prometheus to send alerts to the v2 endpoint
instead of the defautl v1 endpoint.

Lots of alerts are based on ratios (eg. disk usage), and humans are used
