`delete_all` doesn't support limit, so you'd need to subquery
that. And instead of subquerying with `where(id: query)`, it's better
to use an `INNER JOIN`. This method also works with MySQL, while
subquerying doesn't (without another layer of subquerying)

Fix link to blog posts in docs

See merge request gitlab-org/gitlab-ce!21820

The 9.4 to 9.5 and 9.5 to 10.0 guides missed a closing backtick. This
was corrected in the 10.0 to 10.1 guide, from which subsequent guides
were written without the error.

Due to a missing `s`, a link to the blog archive
for releases was broken.

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.
