Review comment:
AbfsRestOperation is not supposed to have any API specific
implementations or handling. Come up with a LeaseRetryPolicy that will be used
when executing operations that pass in leaseId. That can control retry count to
2 or how many ever reduced number of retries needed. Post that, if the request
still fails, retry policy should exit AbfsRestOperation and abfsClient should
take care of retrying from the respective method post updating request headers.
