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
Shouldn't this setup also run if running the test live (i.e. not mocked, but also not recording)?
