Feature: Runner tag filter for admin view

See merge request gitlab-org/gitlab-ce!19740

Due to performance reasons we cannot use the type filter on the tags.
The table for ActsAsTaggableOn is too big and too unoptimized, such that
the queries time out on production.

See the discussion
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/19740#note_120087938
for more info.

The query generated by ActsAsTaggableOn `@taggable_type.all_tags` is
very inefficient (joins too much, grouping, inner select, ...).

the potential number of available runner tags is too large to load it
statically to a dropdown. we use the same lazy loaded dropdown as is
used for the users dropdown already.
