Fix Admin area user access level radio button labels

See merge request gitlab-org/gitlab-ce!31154

In the admin user edit form, access level radio button labels didn't have
the correct 'for' value. Clicking on the label did not select the radio
button. This makes usability a bit nicer since the click area is increased
when the label is clickable.

This is the first step in providing a fault-tolerant and distributed
Redis caching store. We disable compression to avoid introducing a
change that could have an adverse effect in production.

Note that we won't be able to take advantage of the fault-tolerance and
distributed features yet until we solve
https://gitlab.com/gitlab-org/gitlab-ce/issues/64829.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/64794

!31480 does not fully restore compatibility because another Ruby 2.6
feature besides `Enumerable#filter` was used in commit ca5cd7b7. The use
of `Enumerable#to_h`'s block is now replaced by an explicit
`Enumerable#map` call.

Error message:

	TypeError (wrong element type Gitlab::Git::Branch at 0 (expected array)):
  	app/controllers/projects/branches_controller.rb:53:in `to_h'

See https://bugs.ruby-lang.org/issues/15143.

Fixes #64143.
