Add system note when due date is changed

Closes #38208

See merge request gitlab-org/gitlab-ce!21628

This is similar to https://gitlab.com/gitlab-org/gitlab-ee/issues/7511, but
the root cause is https://gitlab.com/gitlab-org/gitlab-ce/issues/51268.

Update invite_group_spec to be consistent with EE

See merge request gitlab-org/gitlab-ce!21608

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/21386 re-introduced
the explicit creation of the project name separate from the project path.
Filling in the name does automatically populate the path, but the reverse
is not true. We now fill in the name instead of the path.

Closes https://gitlab.com/gitlab-org/gitlab-qa/issues/322

Resolve "Remove Gitlab::GitAccess#authed_via_jwt?"

Closes #51267

See merge request gitlab-org/gitlab-ce!21610

If one spec disables the usage ping in the in-memory application settings
(e.g. spec/features/usage_stats_consent_spec.rb), then this spec will
fail. To work around this problem, we enable the usage ping explicitly
in the setup phase.

Vue MR Page - Data structure update

See merge request gitlab-org/gitlab-ce!21062

The check for the "Invite member" tab for the test
where a project cannot be shared with groups isn't
relevant, and needs to be removed since in EE the
visibility rules for the tab are different due to
both the group and membership lock capabilities.

Fix group labels page timeout if many projects and labels

Closes #51221

See merge request gitlab-org/gitlab-ce!21594

When a container registry has many tags, it's easy for the DELETE call to take more
than 60 seconds and fail. This can also leave the registry in a bad state with
null bytes since some of the images have been deleted with tags still pointing to them.
In addition, we have to prevent users from accidentally initiating the delete multiple
times or this could leave the registry with orphaned tags.

This commit also adds a flash message to notify the user the registry is scheduled
for deletion.

Closes #49926, #51063
