HBASE-19828 Flakey TestRegionsOnMasterOptions.testRegionsOnAllServers 

Rename the PE Worker threads.

Send an interrupt if worker taking a long time to go down
(it may be RPC'ing out to a dead server, retrying so
interrupt). Also join on the ProcedureExecutor shutting down.
This will make problems shutting down more obvious.

Disable TestRegionsOnMasterOptions. Master carrying Regions is broke.
