params: make method on node and port to enum params

Browse source 
Do not pass the params of the node in the node_info, instead,
make a method to enumerate the params. This makes it possible for
clients to only enumerate what they need and when they need it.
Improve introspection of a port, add the name and properties.
Add an enum_param method on the port that can be used to enumerate
port formats.
Change -monitor and -cli and add support for enum_params on the node
and port.
