Defining an option to override the user for a run step is too much fine grained
and, for consistency, will require to do the same also for the other steps
(clone, *workspace etc...).
Remove it since it's probably enough to define it at the task level.
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).
