Dynamic creation of disk pools

[metsuke0]

Is your feature request related to a problem? Please describe.
I autoscale my EC2 nodes and I need disk pools on every node with a certain label.

Describe the solution you'd like
Given certain topology/label constraints, a disk pool can be allocated to a node upon startup.

If a node is terminated or stopped, the disk pool would remain, along with its PVs and PVCs. When a new node is created, the disk pool would be assigned to that node along with the PVs and PVCs.

Describe alternatives you've considered
Portworx does this. Their StorageCluster kind is a good example of it working well.

kind: StorageCluster
spec:
  cloudStorage:
    deviceSpecs:
      - type=gp3,size=500...
    placement:
      nodeAffinity: ...
