Determine if callbacks are allowed in remote sessions

Currently we allow callbacks by injecting a cmdlet into the initial session state. Can we do something similar for remote sessions?

Start by reading host.cpp at lines 418-435, where callbacks are injected into the initial session state. Investigate whether the same approach applies to remote sessions and define the expected callback behavior; done means reaching a clear feasibility conclusion and identifying the required implementation scope.
