Ian Wienand 814e4be128 Ansible roles for backup
This introduces two new roles for managing the backup-server and hosts
that we wish to back up.

Firstly the "backup" role runs on hosts we wish to backup.  This
generates and configures a separate ssh key for running bup and
installs the appropriate cron job to run the backup daily.

The "backup-server" job runs on the backup server (or, indeed
servers).  It creates users for each backup host, accepts the remote
keys mentioned above and initalises bup.  It is then ready to receive
backups from the remote hosts.

This eliminates a fairly long-standing requirement for manual setup of
the backup server users and keys; this section is removed from the
documentation.

testinfra coverage is added.

Configure a host to be backed up

This role setups a host to use bup for backup to any hosts in the backup-server group.

A separate ssh key will be generated for root to connect to the backup server(s) and the host key for the backup servers will be accepted to the host.

The bup tool is installed and a cron job is setup to run the backup periodically.

Note the backup-server role must run after this to create the user correctly on the backup server. This role sets a tuple bup_user with the username and public key; the backup-server role uses this variable for each host in the backup group to initalise users.

Role Variables

The username to connect to the backup server. If this is left undefined, it will be automatically set to bup-$(hostname)
