Greg Mierzwinski 3ee37077ea Bug 1890318 - Add dynamic metric documentation to perfdocs. r=perftest-reviewers,aglavic DONTBUILD
This patch adds the ability to document metrics dynamically. The metrics are documented in the config YAML file for each framework, and then defined in a metrics.rst file. Two things are expected to be found in the framework docs now if they want to use dynamic metric documentation:
* A metrics.rst file that contains a `{metrics_documentation}` entry somewhere to insert the built documentation.
* A `{metrics_rst_name}` entry somewhere in the top-level/index.rst file so that a link can be produced to the metrics documentation.

The metrics documentation is specific to each framework. See the schema for the metrics for what is expected in this field. At the same time, the dynamic documentation for Raptor is generated here. Each metric in Raptor contains a list of all the tests that use (alert on) the specific metric. The tests link back to the test definition, and the metrics defined in the tests also link to the metric definitions.
