Simone Gotti c1ff28ef9f *: export clients and related types
Export clients and related packages.

The main rule is to not import internal packages from exported packages.

The gateway client and related types are totally decoupled from the gateway
service (not shared types between the client and the server).

Instead the configstore and the runservice client currently share many types
that are now exported (decoupling them will require that a lot of types must be
duplicated and the need of functions to convert between them, this will be done
in future when the APIs will be declared as stable).
