feat(3p/nix): Add main function for grpc daemon r/1472

Implement the main function for the new, proto-based nix daemon. This
mostly replicates the behavior of the previous nix daemon - it starts a
grpc server listening on the same nix socket path and supports the same
set of options - with the exception of --stdio, which has been renamed
to --pipe and documented in the man page.
