Refactor the Azure plugin
Browse files Browse the repository at this point in the history 
Both Kopia repository and Azure plugin need to interact with Azure storage. In order to keep in sync with the new features for both these two places and remove duplicated code, PR vmware-tanzu/velero#6686 makes the common code as util functions in Velero repository.

This commit refactors the Azure plugin based on these util functions.
