Issues:
OSDs flaps because of insufficient heartbeat timeout on
large clusters
Replica configured is overwritten when upgrade or setup_storage
is run again.
Live migration provision doesnt work if there are multiple subnets
upgrade or setup storage creates new mons when the storage-compute
order changes in the testbed.py
if only ssd-disks is specified the pgs are stuck.
If osd is not running, the remove disk fails as its trying
to stop the osd.
Fix:
Configured heartbeat based on the replica size.
Added a configuration variable 'storage_replica_size' in testbed.py
to specify the replica
Addded fix to support multiple subnets for live migration.
The current monitors are not taken into account for the total
monitors. Fix added to take existing monitors into account.
If there is only 'ssd-disks', code added to treat as 'disks'.
The quota for cinder is to be set based on the total space and
not the current available space.
Check added to stop osd only if osd is running.
