This cop prevents you from using file in API, it points you to the
development documentation about workhorse file acceleration.

This functionality is available in the /autocomplete users pseudo-API.
We're attempting to replace that with the canonical API, so it needs
support for this parameter too.

Expose time since starring on project/:id/starrers API endpoint; exclude private profiles here as well

Fix API endpoint for starred projects of a user; add info about starred projects on profile to documentation

Previously the Housekeeping button and API would use the counter of last
pushes to determine whether to do a full garbage collection, or whether
to do one of the less comprehensive tasks: a full repack, incremental
pack, or ref pack. This was confusing behavior, since a project owner
might have to click the button dozens of times before a full GC would be
initiated.

This commit forces a full GC each time this is initiated. Note that the
`ExclusiveLease` in `HousekeepingService` prevents users from clicking
on the button more than once a day.

The `#reload` makes to load all objects into memory,
and the main purpose of `#reload` is to drop the association cache.

The `#reset` seems to solve exactly that case.

This backports various parameter changes EE makes to API::Projects,
along with moving some code around to make it easier to extend in EE.
