                during instance creation, it cannot be set or changed after the instance
                has been created.

            sources or targets for network firewalls and are specified by the client
            during instance creation. The tags can be later modified by the setTags

              - Specifies a fingerprint for this request, which is essentially a hash
                of the metadata's contents and used for optimistic locking.
              - The fingerprint is initially generated by Compute Engine and changes
                after every request to modify or update metadata. You must always
                provide an up-to-date fingerprint hash in order to update or change
