Add management REST functions to dvmfne

[W3AXL]

For dvmprov to be able to provision and manage the CFNE, we need at a minimum the following functions in the REST API:

• Query/Add/Delete RID entries in white/blacklists
• Query/Add/Delete routing rules
• Query/Add/Delete peers
• Configure master & system parameters

Configuration changes via REST should also be saved in the local fne config ymls, so they persist.

Mostly done, future REST updates and changes will be handled individually in the dvmhost project
