Auto-generate /srv/pillar/ceph/master_minion.sls file

[noelmcloughlin]

The DeepSea README has this step.

Check that the file /srv/pillar/ceph/master_minion.sls on the Salt master points to your Salt master. If your Salt master is reachable via more host names, use the one suitable for the storage cluster. If you used the default host name for your Salt master in the example domain, then the file looks as follows:

master_minion: salt.example

The file /srv/pillar/ceph/master_minion.sls should be created by this formula.

And create this file used in stage.1

root@ubuntu1804:~# curl -o /srv/pillar/ceph/proposals/policy.cfg https://raw.githubusercontent.com/SUSE/DeepSea/master/doc/examples/policy.cfg-rolebased

root@ubuntu1804:~# vim /srv/pillar/ceph/proposals/policy.cfg

And create/modify cluster settings for stage.2

/srv/pillar/ceph/proposals/config/stack/default/ceph/cluster.yml
