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.

Document the behavior of an empty `ec2_sd_config` `region` setting. If this is

If it is blank and instance region metadata is not available, an error will

By default, OpenStack SD only queries for instances
from specified project. To discover instances from other
projects, users have to add more openstack_sd_configs for
each project.
This patch adds `all_tenants` <bool> options to
openstack_sd_configs. For example:
- job_name: 'openstack_all_instances'
openstack_sd_configs:
- role: instance
region: RegionOne
identity_endpoint: http://<identity_server>/identity/v3
username: <username>
password: <super_secret_password>
domain_name: Default
all_tenants: true

This adds support for basic authentication which closes#3090
The support for specifying the client timeout was removed as discussed in https://github.com/prometheus/common/pull/123. Marathon was the only sd mechanism doing this and configuring the timeout is done through `Context`.
DC/OS uses a custom `Authorization` header for authenticating. This adds 2 new configuration properties to reflect this.
Existing configuration files that use the bearer token will no longer work. More work is required to make this backwards compatible.
