Required. The full resource name of the sink to update,
including the parent resource and the sink identifier: ::
"projects/[PROJECT_ID]/sinks/[SINK_ID]"

Optional. See
sinks.create][google.logging.v2.ConfigServiceV2.CreateSink]
for a description of this field. When updating a sink, the
effect of this field on the value of writer_identity in
the updated sink depends on both the old and new values of
this field: - If the old and new values of this field are
both false or both true, then there is no change to the
sink's writer_identity. - If the old value is false and
the new value is true, then writer_identity is changed
to a unique service account. - It is an error if the old
value is true and the new value is set to false or
defaulted to false.
