Remove unused constant

See merge request gitlab-org/gitlab-ce!21810

This changes the hard limit of 50 to a soft limit of 50, with the new
hard limit being 72 characters. This gives people a bit more space,
while still (hopefully) guiding them towards subject lines that are
roughly 50 characters long.

When there are many tags in a container repository, deleting them
can exceed the default 60 second idle-in-transaction timeout in
Sidekiq. We now explicitly delete them in the DestroyService
before destroying the model.
