Azure Storage sprint 40: support sas token used in operations and get/set service properties

Azure Storage sprint 40:

- Support sas token to be used in blob, file, table and queue operations by parameter --sas or --source-sas/--dest-sas (blob copy)

- Support get and set storage service logging properties

- Support get and set storage service metrics properties
Question (not on this code, doesn't affect this pr) is this todo still an issue since you're using the new storage SDK now?
