Etags are used for optimistic concurrency control as a way to help prevent simultaneous
updates of a policy from overwriting each other. It is strongly suggested that systems make
use of the etag in the read-modify-write cycle to perform policy updates in order to avoid
race conditions. An etag is returned in the response to getIamPolicy, and systems are
expected to put that etag in the request to setIamPolicy to ensure that their change will be
applied to the same version of the policy. If no etag is provided in the call to
setIamPolicy, then the existing policy is overwritten blindly.
