Store additional OSD information in ZK

Browse Source 
Ensures that information like the FSIDs and the OSD LVM volume are
stored in Zookeeper at creation time and updated at daemon start time
(to ensure the data is populated at least once, or if the /dev/sdX
path changes).

This will allow safer operation of OSD removals and the potential
implementation of re-activation after node replacements.
