This PR is based on severely outdated version of 10.6. Please rebase against 10.6 head.
This patch adds a mechanism for setting the priority of WSREP applier and rollbacker threads via a new dynamic system variable "wsrep_applier_priority". By default, the priority and scheduling policy are set to 0 and "other", respectively. This is encoded by the string "other:0" in the "wsrep_applier_priority" variable. The other scheduling policies are "rr" and "fifo". See sched(7) for details.
