m2:add unit tests for new code & add azure PV support & upsizing

[pydevops]

@dustinbarnes

• Added Azure PV support
  • new storage class for PV
  • updated documentation on backup and restore
• Added Azure PV upsizing issue & workaround.
• Refactored the GCS backup and restore code into pkg/storage and become testable, and make sure the unit test coverage in pkg/store is over 80% for the relevant code.
  • use fake/mock client for GCS, k8s client-go and controller-runtime client.

This is looking solid. One question: Did you mean to commit these tar.gz files?

pkg/storage/testdata/backup/20190124T234601Z.s7.tar.gz -- there's a few of them.

I copied some sample data here for unit testing. What is the best practice of using them? thanks

Eh, I think that's sufficient. I just wanted to make sure we weren't putting any extra cruft into the repo.
