Optional. Read mask is used for a more granular control over what the API
returns. If the mask is not present all fields will be returned except
[Queue.stats]. [Queue.stats] will be returned only if it was  explicitly
specified in the mask.

<code>.google.protobuf.FieldMask read_mask = 2 [(.google.api.field_behavior) = OPTIONAL];
