Resolve "Sidebar styling updates"

Closes #54814

See merge request gitlab-org/gitlab-ce!23816

In a merge request with many discussions, the avatar URL can be called
thousands of times, inflicting a significant performance penalty
especially when avatars are stored in object storage. To mitigate this
problem, we can just cache the generated path any time it is requested.

Leave object pools when destroying projects

Closes gitaly#1415

See merge request gitlab-org/gitlab-ce!23869

This action doesn't lean on reduplication, so a short call can me made
to the Gitaly server to have the object pool remove its remote to the
project pending deletion.
https://gitlab.com/gitlab-org/gitaly/blob/f6cd55357/internal/git/objectpool/link.go#L58

When an object pool doesn't have members, this would invalidate the need
for a pool. So when a project leaves the pool, the pool will be
destroyed on the background.

Fixes: https://gitlab.com/gitlab-org/gitaly/issues/1415
