Specifically, if do the following:
* Enter global maintenance (hosted-engine --set-maintenance-mode
--mode=global)
* init 0 the engine
* systemctl stop ovirt-ha-agent ovirt-ha-broker libvirtd vdmsd
and then run "sanlock client status" I see:
# sanlock client status
daemon c715b5de-fd98-4146-a0b1-e9801179c768.xion2.smar
p -1 helper
p -1 listener
p -1 status

Waiting a few minutes does not change this state.
The earlier data I shared which showed HostedEngine was with a different
test scenario.
