Title: Update of installation.md

Installation of postfix without confirmation can delete existing qmail server.

libmysqlclient16-dev is needed for the mysql gem installation.

Version of redis-server needs to be 2.0+. There will be no obvious error/warning message during installation or running gitlab if it's below. Only sidekiq.log will show the problem.
