Add handling special case for contrail_health module

This patch covers special case for contrail_health module, when
we have contrail-status and doctrail utilities both available on host.
This case happens during contrail upgrade procedure (3.2 -> 4.0), when
new version of contrail services have already started inside containers and
old packages with contrail-status util are still present on host.
