lib: Manage multiple flows with a single CDAP instance

You can now add multiple flows to a CDAP instance. This will simplify
sending messages to different peers (e.g. for syncing the RIB). A
request will now return an array of keys terminated by
CDAP_KEY_INVALID. Removes the enum from the CDAP proto file to just
take the opcode as an integer.
