QE automation required for OADP on ROSA w/ STS

Description of problem:

There was some previous work done to enable OADP w/ ROSA using STS authentication and permissions.  The SRE ROSA team has created step by step instructions that we need to automate as part of the QE regression suite.

The workflow [1] needs to continue to work from release to release of OADP.
