Make MdsalServerStrategy implement only ServerDataOperations

MdsalRestconfStrategy is acting as the root of a MdsalRestconfServer,
which is really a historical thing.

MdsalServerStrategy is a new class which takes over the role of the root
ServerStrategy, with a clear relationship with MdsalRestconfServer.

This moves a chunk of logic out of (Mdsal)RestconfStrategy, bringing
RestconfStrategy making it just an implementation of
ServerDataOperations.

Refactor ServerRpcOperations implementations

We support both local and DOMRpcService-mediated RPC implementations,
but have the relationship rather hard-coded.

InterceptingServerRpcOperations provides the ability to look up a
RpcImplementation and delegate to it. If the lookup fails, the request
will be forwarded to a downstream ServerRpcOperations.

A default downstream is provided as NotSupportedServerRpcOperations,
which always completes the request with an ErrorTag.NOT_SUPPORTED
error.

We also split out DOMRpcService-based implementation into
MdsalServerRpcOperations and have RestconfStrategy instantiate a
combination of these two.

The same is true for a DOMActionService-based implementation, named
MdsalServerActionOperations.

Fix TCPClient.connect() initialization

The firing of ChannelFutureListeners and handler callbacks is slightly
diifferent in that listeners may be fired in a separate pass, but
handler callbacks are guaranteed to fire during event reception.

We really want to fire when the channel becomes active, similarly to the
no-op we have via ConnectChannelInitializer -- thus immediately updating
the pipeline.

This ensures that NettyIoSession.channelActive() has been invoked before
Netty can deliver any events to it.
