> We have startup timestamp for RM already, but don't for NM.
> Sometimes cluster operator modified configuration of all nodes and kicked off 
> command to restart all NMs.  He found out it's hard for him to check whether 
> all NMs are restarted.  Actually there's always some NMs didn't restart as he 
> expected, which leads to some error later due to inconsistent configuration.
> If we have startup timestamp for NM,  the operator could easily fetch it via 
> NM webservice and find out which NM didn't restart, and take mannaul action 
> for it.
