wirepeer: subclass new `repository.ipeer{,legacy}commands` Proctocol classes This is the same transformation as 3a90a6fd710d did for dirstate, but the CamelCase naming was already cleaned up here. See 4ef6dbc27a99 for the benefits of explicit subclassing. PyCharm is flagging the `wirepeer.getbundle` function with: Type of 'getbundle' is incompatible with 'ipeercommands' I've no idea why- maybe it's because it can infer a `unbundle20 | cg1unpacker` return there, or maybe it's the kwargs. Something to keep an eye on, but pytype doesn't complain. Since we're direct subclassing here and there are only a few methods on these interfaces, also make them abstract like was done in ef119f914fc1.
