Need to set uid/gid for 'backup' user to 801:801 for consistency across hosts.

ansible-build/remote-backup.yml

Line 18 in 1dc314c

Eg.
$ id backup
uid=801(backup) gid=801(backup) groups=801(backup)

User creation is generally here:

ansible-build/mysql.yml

Lines 94 to 100 in 1dc314c

	# manage automatic mysqlbackups
	- name: Add backup user
	user:
	name: backup
	comment: Mysql Backup
	shell: /sbin/nologin

But also duplicated here:

ansible-build/ojs.yml

Lines 96 to 100 in 1dc314c

	- name: Add backup user
	user:
	name: backup
	comment: Mysql Backup
	shell: /sbin/nologin

(particularly if OJS were ever to have a remote db)

As this is for not only performing MySQL backups now, should the comment be updated as well?
