Add feature to support transfer of volume from one pool to another #235

Closed vatsa287 closed 2 years ago

The existing(https://github.com/kadalu/moana/pull/233) support to rename a volume can used to add this feature. Note: There should not be a volume already present in that volume in a pool which is being transferred to.

After adding comment, I realized that this is very tricky since nodes are part of the first pool and those needs to be migrated.

Validations required are:

Target Pool exists
Volume with same name not exists in target Pool
Nodes are not part of any other Volume in the same pool.

After Validation,

Update nodes table to new Pool.
Update Volumes table, distribute groups and Storage units table
