Fix overcloud_health_checks on OSP17

This patch fixes several issues affecting OSP17 when faults/ha tests
are executed:
1) nova_libvirt container is renamed to nova_virtqemud
2) ovn_l3_mode is deprecated from neutron configuration
3) ovn dbs resources status names changes from Master/Slave to
   Promoted/Unpromoted
