Add support for executing RPCs
Creating a temporary YangAccess for RPC input means I need to somehow
give the right libyang schemas. For that reason I supply a callable
which is able to fetch the schema and create a YangAccess instance for
ProxyDatastore.
The ProxyDatastore class now has a simple mechanism for deciding whether
to use the normal datastore and the temporary based on a path prefix.
