Will now support two extra parameters: address and codec. For *internal
connections, the birpc.Service object will be retrieved from rpcParamsMap
from utils. Supported codecs: <*gob|*json|*http_jsonrpc> (ingored for
*internal address).
Action does not bother with setting defaults anymore, lets the API
handle them.
Improve action comments.
Add unit tests for the action. UnregisterRpcParams' implementation was
required.
Updated *alter_sessions action tariffplan for radius coa integration test
to include address and codec.
Some birpc clients that are set up in integration tests were still registering
a SessionSv1 object. Updated them to register an AgentV1 object instead.
