** [tickets:#1725] AMF: Recover transient SUSIs left over from headless**

**Status:** fixed
**Milestone:** 5.1.FC

This ticket is more likely an enhancement that targets on how AMFD detect and 
recover the transients SUSI left over from headless. There are three major 
(1) - Cluster goes headless, su/node failover on any payloads can happen, or 
any payloads can be hard rebooted/powered off by operator, then cluster recover
(2) - issue admin op on any AMF entities, cluster goes headless. During 
headless, the middle HA assignments of whole admin op sequence between AMFND 
and components could be:
    (2.1) The assignment completes, component returns OK with csi callback, 
then cluster recover
    (2.2) The assignment is under going, then cluster recover. The assignment 
afterward could complete, or csi callback returns FAILED_OPERATION or error can 
also happen
At the time cluster recover, amfd has collected all assignments from all 
amfnd(s). These assignments can be in assigned or assigning states whilst its 
HA states do not conform its SG redundancy. Any of (1) (2.1) (2.2) can happen 
in a combination, which means while issuing admin op (2), cluster go headless 
and any kinds of failover (1) can happen during headless.
