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.

Setup backup server

This role configures backup server(s) in the backup-server group to accept backups from remote hosts.

Note that the backup role must have run on each host in the backup group before this role. That role will create a bup_user tuple in the hostvars for for each host consisting of the required username and public key.

Each required user gets a separate home directory in /opt/backups. Their authorized_keys file is configured with the public key to allow the remote host to log in and only run bup.
