Extract streams helpers from command package to their own package to remove a cyclic dependency from command to internal/containerizedengine

Aliasing old types
* streams.InStream -> streams.In
* streams.NewInStream -> streams.NewIn
* streams.OutStream -> streams.Out
* streams.NewOutStream -> streams.NewOut
