Bug Description

As seen at https://groups.google.com/d/msg/percona-discussion/-/fInV4T3hoTAJ : we already have desync functionality utilized in RSU. However it is not exposed to client explicitly, which may be useful in some situations. Exposing this functionality to client still preserves the HA properties of the cluster as opposed to using async master-slave replication.

Should be easy to do either via /*! WSREP_DESYNC */ comment on the query or SET GLOBAL wsrep_desync=1 variable.
