Replaces .card-header > hX.card-title with hX.card-header to remove
.card-title. At a occurrence where bold styling is not necessary,
div.card-header is used instead.
By full removal of .card-title at the moment, all workarounds for
BS4's card-title are removed as well.

Tests for these new helper methods

This adds counters for build artifacts and LFS objects, and moves
the preexisting repository_size and commit_count from the projects
table into a new project_statistics table.

The counters are displayed in the administration area for projects
and groups, and also available through the API for admins (on */all)
and normal users (on */owned)

The statistics are updated through ProjectCacheWorker, which can now
do more granular updates with the new :statistics argument.

Groups can enable/disable LFS, but this setting can be overridden at the project level. Admin only

permissions/permissions just links to user/permissions since
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/5210

And create new Project#requesters, Group#requesters scopes.
