RAM Requirements update

512MB of RAM is not enough to install using omnibus-gitlab.

Installation will fail in very random places.

Manual installation might also fail with this low amount of RAM.

Performance improvements

Push 1k commits cause 1k sql queries to collect commit author. But this variable was used only in 20 commits (from 1000).
So we did 980 sql queries without using it. This MR fixes it.

	CHANGELOG

In e23a26ae (and later 1bc99369) the API for Gitlab::LDAP::Adapter was
changed. I assume this rake task was an oversight in the refactoring of
the changed class.

While being on it, I noticed that already blocked users cannot be
blocked again.

Add issue edited timestamp

Comments already have this feature.
So, I think, issues should also have it.
