Reduce delay in destroying a project from 1-minute to immediately

This 1-minute delay was causing confusion among customers. Was there a reason this needed to be 1 minute?

Auto-set title for branches created from issues

This sets the title for a new MR to 'Resolves "$issue-title"' when:
- The source branch for the MR begins with a value iid.
- The MR has more than one commit in its diff (if there's one commit, keep using the commit's first line).
- The iid does not point to a confidential issue.

Single commit:

Multiple commits:

Closes #14564

Use outer join for issues ordering by milestones due.

This MR contains an implementation for Solution 1 suggested in #14183 

Ordering by Milestone due sooner/later ("milestone sort") filters issues without a milestone, which can let users feel like disappearing issues without a milestone.

See merge request !3872

If a branch starts with an issue's IID, followed by a hyphen, the
description will be updated to say that is closes the issue. This also
updates the title of the merge request to 'Resolves "$issue-title"', as
long as:
- There is more than one commit in the merge request (if there is only
  one commit, the commit's title will be used as before)
- The issue's IID is valid for the project

Use tag_exists? in GitAccess#protected_tag?

This will fail until https://gitlab.com/gitlab-org/gitlab_git/merge_requests/81/ is merged. Adding this should speed up checking for tags in `Gitlab::GitAccess` as it no longer needs to retrieve the entire list of tags.

See https://gitlab.com/gitlab-org/gitlab-ce/issues/14280 for more information.

See merge request !3983

Previously this method would directly receive the output of tag_name().
This method could either return a String or nil. In the previous setup
this would somehow magically work but because Rugged::TagCollection#[]
doesn't accept nil values it started to fail.

To work around this the elsif in change_access_check() assigns the
result of tag_name() to a local and then _only_ calls protected_tag?()
if the tag name is not nil. The extra parenthesis are put in place to
ensure that things are parsed correctly, without these the code would be
parsed as follows:

    elsif tag_ref = (tag_name(ref) && protected_tag(tag_ref))

During runtime this would basically resolve to:

    elsif tag_ref = (tag_name(ref) && protected_tag(nil))

This is because when you refer to the variable you're assigning _in_ the
assignment Ruby returns nil instead of raising an error.

This removes the need for retrieving the entire list of tags just to
check if a specific one exists.
