[Openstack-operators] Ceph puppet module

osds can only come up once at least the initial mon services are
running and formed a quorum, so lets concentrate at getting the mons
If using cephx authentication all mon services need to be started at
the same time (a similar time), translated to puppet this means all
the puppet runs on the mons need to be started within a certain time
frame (before the timeout of the mons trying to connect each other).
The reason being that the mons first need to form a quorum before most
of the further actions can happen.
Can you provide some additional information about your setup? Specifically:
- what's your exact puppet modules configuration
- what version are you running?
- please be aware that running on Ubuntu 14.04 is currently not
getting integration tested (currently only Ubuntu 12.04 and CentOS 6
are tested, support for CentOS 7 is in the works).
- how many mons are you running
- are the osds running on the same hosts as the mons
- do you use a single network, or do you use separate cluster/public networks
- do you have a firewall running, if yes, can you share your firewall
configuration (iptables -vnL)
- what exactly did you need to patch?
