Manual steps for pool creation if status is Init or PoolCreationFailed, in case a node goes down and new nodes comes up.

[ChandanSagar]

With some cloud service providers, if a node goes down, new node will be created with a new set of disks. In that case, will OpenEBS automatically trigger blockdevice reconfiguration and rebuild the volume if auto node pool creation is enabled. This was supported till 1.2 release.

With the assumption that a new node came up with the same label and blockdevices names are the same after recreating the node. Post 1.2, manual steps are required to set the status on CSP as Init. Manual steps should be documented in docs.
