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.

In e23a26a (and later 1bc9936) 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.

Better merge request manual instructions

I noticed the current instructions for manually merging a merge request that was submitted from a fork could create unnecessary merge requests or strange history. Imagine this:

1. Alice creates a repository and commits / pushes a single commit with SHA1 `A` to `master`.
2. Bob forks this repository and creates a new branch `myfeature` on `master` (`A`)
3. Alice commits `B` to `master` (which has the parent `A`)
4. Bob creates two commits on `myfeature` `P` and `Q`.
5. Bob submits the merge request to merge his `myfeature` into Alice's `master` branch.
6. Alice follows the manual merge request instructions:
  1. `git checkout -b bob/repo-myfeature master`
  2. `git pull http://... myfeature`

The branch `bob/repo-myfeature` was created from Alice's current `master`, which was `B`. When the `pull` is executed, git will fetch Bob's branch and then merged the fetched branch `Q` into the current branch's location `B`. This creates an unnecessary merge commit from `master` into the branch Alice is trying to merge. No harm is done, but the history is a bit messier.

This is even worse if Alice has set `git pull` to rebase by default. In this case, the commit `B` is rebased on top of `Q`. When Alice checks out `master` and merges in the branch, there will actually be a duplicate `B` commit.

These new instructions instead tell the user to fetch Bob's `myfeature` branch. This will fetch the necessary commits `P` and `Q` and create a temporary ref `FETCH_HEAD` pointing to `Q`. Alice will then create her local `bob/repo-myfeature` branch starting at `FETCH_HEAD`. No unnecessary merge commits, and no accidental rebasing.
