### Description of PR
When RM not in HA mode, and RM restart, we handle reading the exclude file
and keep state of decommission requested NMs. The in memory state of NMs
become proper to decommissioned.
But in HA mode, when standby become active, this state transition dont
happen properly. The decommissioning NMs will get kill request from RM when
those NMs heart beat to new Active RM. But the in memory state do not become
decommissioned. So the node state API dont give proper state of DECOMMISSIONED.
This PR fixes this issue.
### How was this patch tested?
Manually tested with RM failover while some of the NMs are in graceful
decommissioning state.
