internalpb: move satellite specific protobuf types storj/storj

We have some types that are only valid for satellite usage. Such types are SatStreamID and SatSegmentID. This change moves those types to storj/storj and adds basic infrastructure for generating code. Change-Id: I1e643844f947ce06b13e51ff16b7e671267cea64
