Allow explicit configuration of TTRPC address

Previously the TTRPC address was generated as "<GRPC address>.ttrpc".
This change now allows explicit configuration of the TTRPC address, with
the default still being the old format if no value is specified.

As part of this change, a new configuration section is added for TTRPC
listener options.
