Add Atlassian Bamboo service

Close #717

This closes #717:

Add documentation changes to:

 * Set the permissions of the unix socket properly
 * Create the directory for the socket
 * Make sure tmpfiles.d persists said directory

The first change makes sure gitlabl can connect to the socket. The latter two avoid redis from failing to start on systemd-based systems, including recent versions of Debian.

You may probably want to cherry-pick this into the documentation for the latest stable release.
