> Communication between Collector and NM is via RPC.
> We would do kerberos based authentication for communication between these 2
> components, as of now. Added SecurityInfo implementation for it.
> We can think of adding token based access once collector starts outside of NM.
> Also creation of timeline client within NMTimelinePublisher would be done
> using NM login UGI.
