Matthew Heler 30b57ba671 [CEPH] Fix race conditions with OSD POD initialization 
Under POD restart conditions there is a race condition with lsblk
causing the helm chart to zap a fully working OSD disk. We refactor
the code to remove this requirement.

Additonally the new automatic journal partitioning code has a race
condition in which the same journal partition could be picked twice
for OSDs on the same node. To resolve this we share a common tmp
directory from the node to all of the OSD pods on that node.
