[ceph-osd] Fix the sync issue between osds when using shared disk for metadata

Browse Source 
This is to fix the sync between ceph osds when they are using shared
disk for metadata as they are having conflict while preparing the metadata disk.

we are adding a lock when first osd preparing the sahred metadata disk so that
other osd will wait for the lock, also adding udev settle in few places to get
latest tags on lvm devices.
