[release-4.17] CORS-3753: Allow mocking of the Azure client everywhere

[zaneb]

Currently the Azure client can only be mocked in unit tests of the pkg/asset/installconfig/azure package. Using the mockable interface consistently and adding a public interface to set it up will allow other packages to write unit tests for code involving the Azure client.

This is a backport from #9201

As discussed, I will manually apply the valid-bug label. We are backporting this on the grounds that it affects internal APIs for unit tests only.
