After several discussion on how to add powervs cloud provider support, We decided to fork the existing ibm-cloud-provider and add support for Power VS.

There are two options for creating a cloud-provider-powervs in openshift by forking ibm-cloud-provider

1. forking https://github.com/openshift/cloud-provider-ibm to https://github.com/openshift/cloud-provider-powervs
   
   Problem: Keeping both the repo's in sync, conflicts with naming conventions followed for image names

2. forking https://github.com/IBM-Cloud/cloud-provider-ibm to https://github.com/openshift/cloud-provider-powervs
   
   advantages: there already exist a Cloud Team Rebase Bot to synch the repos, (Example PR: https://github.com/openshift/cloud-provider-ibm/pull/31), we can additionally configure it to sync new power vs fork as well
