Add scale out functionality for SNO Cluster

[sraviteja-maker]

This functionality will help us to scale out the existing SNO Cluster where we can create clusters with SNO+1,SNO+2...SNO+N Deployment models for our internal testing.

It will be very useful for getting around the lab resource constraints.

Can we use the create-inventory playbook to generate the worker entries? Since they have values that could be tedious to copy manually.

[sraviteja-maker]

Good Idea...Let me look into it.
