Previously, only group masters could do this. However, project reporters can
manage project labels, so there doesn't seem to be any need to restrict group
labels further.

Also, save a query or two by getting a single GroupMember object to find out if
the user is a master or not.

Port fix-realtime-edited-text-for-issues 9-2-stable fix to master.

Before this change only last namespace in full path was extracted. It's
fine unless you have a link to submodule under subgroups. In that case
self_url? method returns false and link is processed as external. I
could not find a proper regex to cover all cases and correctly extract
full path to repository and instead used current instance host name
to get correct path to namespace and project.

The following was happening:

1. Workhorse stores an LFS file in /var/opt/gitlab/gitlab-rails/shared/lfs-objects
2. CarrierWave then renames the file to a temporary directory (e.g. /opt/gitlab/embedded/service/gitlab-rails/tmp)
3. CarrierWave then renames the file to its final location (e.g. /var/opt/gitlab/gitlab-rails/shared/lfs-objects)

When the LFS upload path was on a different filesystem than the Rails
installation, step 2 could take a longer than 10 seconds, at which point Workhorse
would time out with "badgateway: failed after 10s: context canceled".

This change makes the work path in the same root as the LFS storage path, preventing moves
across filesystems.

This is controlled with the feature flag gitlab_git_diff_size_limit_increase.
Both of these limits were basically picked arbitrarily in the first place;
disabling the feature flag reverts to the old limits.
