after fm containerization, nfvi would raise openstack
alarms to the fm in pods. while retrieve both platform
and openstack alarms are still required.
So here we add NFVFaultMgmtAPI to get alarms from fm
in pods and gather all alarms in vim strategy steps.
add param "fault_management_pod_disabled" with 'True' as
the default value into config file to disable nfvi get
alarms from containerized fm. it will be removed in future
