Remove support for 1.x volume RPC API

This commit gets rid of most of our Liberty compatibility code in volume
RPC API.

Some shims in volume.manager need to stay through Newton, as I've missed
the opportunity to reorganize arguments in RPC methods when introducing
VolumeV1Proxy. It's a shame, but only thing I can do safely now is to
update TODO comments there.
