WIP - RELENG-941: Display used Releases, unless unused requested

[gabrielBusta]

Issue #2561 - Consider only displaying "used" Releases, unless unused requested

[escapewindow]

As mentioned in the jira ticket, we often add a new release and need to be able to view it/reference it in a rule change. So rather than hiding all unused, I’d prefer if we hid unused-and-older-than-time-threshold.

[gabrielBusta]

This is a toggle switch that hides/un-hides the unused releases. If we need to look at the unused releases we can toggle it. Right now it defaults to hiding the unused releases.

Is it difficult to have the toggle hide/show unused-but-older-than, say, 6 months releases?

[gabrielBusta]

No, it would be straight forward. The toggle could hide/show unused releases older than 6 months.

[gbrownmozilla]

+1 for hiding unused-and-older-than-X; the newly added release is an important consideration. I would think X=a few days would be fine, but 6 months is okay with me too.

I may have spoken too soon. It doesn't look like the Balrog releases keep track of the date they are created. The ShipIt releases are the ones with a "created" timestamp.
