stonith resources in a single node cluster are always stopped

[Michele Baldessari]

On single node clusters puppet stonith should not create the location constraint to avoid the same host, otherwise the stonith resource will always be stopped:
Online: [ overcloud-controller-0 ]
RemoteOnline: [ overcloud-novacomputeiha-0 ]
GuestOnline: [ galera-bundle-0@overcloud-controller-0 rabbitmq-bundle-0@overcloud-controller-0 redis-bundle-0@overcloud-controller-0 ]
