project field can now list project names

[leifmadsen]

If CeilometerEnableTenantDiscovery is enabled, ceilometer samples
will contain project_name field, values from which are populated
in project field.

This change affects 2 dashboards, 'Cloud View' and 'Virtual Machine View',
only these allow switching between openstack projects.

If samples are missing project_name field, the regex for project
variable allows fallback to project field

I'm migrating this change over from infrawatch/dashboards#59 to give us more time to test this and update documentation without adjusting the base dashboards right now, and so that I can close the PR in the dashboards repo and set it to read-only.

Going forward, we want to make the changes here and not have changes land in the dashboard repo and then result in a reversion here. All dashboard changes for the core dashboards should come into the service-telemetry-operator repo as we'll provide management for them in STF 1.5.4.

LGTM

I'm going to throw a do-not-merge label on this until some additional testing can be confirmed. This is in support of vanity names, but I haven't directly tested if this change continues to work with non-vanity OSP configuration. I'm under the impression it should work with both, but without confirmation I'd like to avoid merging this and breaking existing managed dashboards.

Did a little bit of testing today and here's how this looks with instances from multiple projects

Did you get a chance to test how it looks when the OSP has not been configured to send the project names? That seems to be the concern that is blocking the merge.

@csibbitt If ceilometer doesn't send project names it would fallback to project ids. I lost the testing environment long back but I can retest and post a screenshot if needed

(I don't say this often, but) I believe you. :) That seems like the expected behavior to me. Thanks!

I will leave the do-not-merge label on this for now, but the team is welcome to discuss how to manage this going forward.

I tagged this for 1.5.5 (RHOCP 4.16 rebase) for now. I would suggest a tracking issue for this in order to provide the appropriate documentation and manual testing prior to release (QE).

Suggest checking with PM about level of effort to apply to have this landing in a future STF release, and how visible you'd like the feature to be, or whether this can land silently as an easter egg :)
