Display treatment details in the flow view

In ONOS CLI, we are able to tell the difference between immediate instruction and deferred instruction

treatment=DefaultTrafficTreatment{immediate=[TTL_IN{}, MPLS_POP{ethernetType=ipv4}, DEC_MPLS_TTL{}], deferred=[GROUP{group ID=0x7001b000}], transition=TABLE{tableId=60}, cleared=false, metadata=null}

However, immediate and deferred are mixed up in the UI flow view.
It will be nice if we can show them separately.

Also, the transition, cleared and metadata information are missing in the flow view.
