refactor(azure): Solidify the azure fundamentals and namespacing

[sylus]

Hey @zachomedia to make the P.R. review easier I did the file renames etc and in the first commit.

This basically brings everything under the azure section, and also I made sure that every pv and pvc for sharedDisk and azureFile are consistent.

In a future release we can likely collapse all 4 of these files for both pv and pvc and just iterate on the entries from the values.yaml to generate via a range and just have a single file called csi-azure.yaml like the storage class.

But first things first.

Also I got a fair amount of mistakes I wasn't sure how ever worked.

This does have breaking changes, that need to be called out in the changelog.

• Renamed values
• Storage class names are changed (which will cause a delete/re-create)
