The look of the logo is obviously unchanged... This just gets rid of some useless SVG groups that Sketch made.

Only perform LDAP checks for a user after acquiring a lease. Checks

## What does this MR do?

Removes an overlap between the anchor icons on the readme and the sidebar on small screens by reducing the size and the padding of the icon.

## Are there points in the code the reviewer needs to double check?

Probably someone in the Design / UX team will need to review if the solution makes sense.

## What are the relevant issue numbers?

Issue #13334

Optimize Project#ci_service(s)

Related issue: gitlab-org/gitlab-ce#14186

See merge request !3158

Fixed quick submit on note edit

Also removed the cloning of forms for note edits. Instead it just hides/shows the form seeing as it is already there

Closes #14094

See merge request !3151

The method Project#ci_services would load all services into memory
(including _all_ their columns) and then use Enumerable#select to reduce
the list. Project#ci_service in turn would further reduce this list down
to just 1 Service instance.

Instead of doing all this in Ruby we can just offload the work to the
database, reducing the amount of time spent in these methods. These
changes reduce the time of the first call to Project#ci_services from
around 240 ms to around 10 ms, though the final timings will vary based
on database load. Because Project#ci_service is memoized there's no
further overhead introduced by using a database query.

Fixes gitlab-org/gitlab-ce#14186
