thanks @vgratian and @rahulguptajss this is a great start
In addition to the outstanding issues raised in #402 we also need to think more about ZAPI and REST selection algorithm. The node based creator code should be replaced with the struct based cmd/tools/rest/client.go

[rahulguptajss]

resolved merge conflicts.

1: Working on client.go consolidation
2: Pass fields in rest calls.

WIP. I'll move it PR to active when ready for review.
