When rendering a label we want to check 'scoped_label' feature
availability on a project/group where label is being used. For
this reason a label presenter is used in UI and information about
context project/group is passed to this presenter.

Adds to search ILIKE search for milestones title in:
  - Milestones dashboard
  - Group milestones page
  - Project milestones page

One of the steps to deprecate dashboard milestones.
Links do dashboard milestone are replaced with links for each
project milestone

By moving and improving state_count the functions in GlobalMilestone
are no longer used.

Ronald van Zon authored 6 years ago and Ronald van Zon committed 6 years ago

By adding groups to milestones we can now include them
in the count of Open and Closed.

This whitelists all existing offenses for the various CodeReuse cops, of
which most are triggered by the CodeReuse/ActiveRecord cop.

Partially addresses #47424.

Memoize Milestoneish#issues_visible_to_user and counts to reduce lookups
Milstoneish SQL optimised with project, but still slow on GlobalMilestone

This commit adds a number of _html columns and, with the exception of Note,
starts updating them whenever the content of their partner fields changes.

Note has a collision with the note_html attr_accessor; that will be fixed later

A background worker for clearing these cache columns is also introduced - use
`rake cache:clear` to set it off. You can clear the database or Redis caches
separately by running `rake cache:clear:db` or `rake cache:clear:redis`,
respectively.

The frontend will then always use the name as the ID - like previous

* Add Labels tab to Groups
* Add decorator for label so it's aware of Milestones.

With this change we avoid doing N+1 queries when viewing Milestone's
Issues/MRs from a Group context.

Make methods return ActiveRecord Relations instead of Arrays.
