Add embedding support to metrics_dashboard

See merge request gitlab-org/gitlab-ce!29696

This commits adds support for metrics dashboards
for embedding. If the flag 'embedded' is provided
to the environments/id/metrics_dashboard endpoint,
the response will be suitable for embedding in
issues or other content.

This is a precursor for support for embedding
metrics in GFM.

Gitaly data wasn't available to the team, an this change is a first
iteration towards understanding what data we need and how to interpret
it. Later more values will be added.

For now the most important thing is the filesystem String Array, as that
includes data on ext4 exposure and NFS.
