Clark Boylan 3efcc957d6 Update bup excludes for zuul-scheduler
On our zuul-scheduler host the /root/.bup dir is extremely large. On
closer examination this appears to be due to large file indexes. Looking
at the host we've noticed that we are backing up the status.json backups
as well as job runtime files which can and do change frequently which
could lead to very large file indexes.

We don't actually need to back these up permanently so exclude them from
bup's list. the /var/lib/zuul/backup dir contains status.json backups
which are really only useful in the immediate time frame and the times
db is something we can live without if we lose it (we'll just build a
new one).

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)
