Sarah Yasonik 7d393bd852 Expose metrics element for FE consumption
Adds GFM Pipline filters to insert a placeholder in the generated
HTML from GFM based on the presence of a metrics dashboard link.

The front end should look for the class 'js-render-metrics' to
determine if it should replace the element with metrics charts.
The data element 'data-dashboard-url' should be the endpoint
the front end should hit in order to obtain a dashboard layout
in order to appropriately render the charts.

# These filters transform GitLab Flavored Markdown (GFM) to HTML.
# The nodes and marks referenced in app/assets/javascripts/behaviors/markdown/editor_extensions.js
# consequently transform that same HTML to GFM to be copied to the clipboard.
# Every filter that generates HTML from GFM should have a node or mark in
# app/assets/javascripts/behaviors/markdown/editor_extensions.js.
# The GFM-to-HTML-to-GFM cycle is tested in spec/features/copy_as_gfm_spec.rb.
