rpc: Introduce CLI's --action-script analogue

Browse Source 
Service shouldn't call client provided scripts, as it
creates a security issue (client may be unpriviledged,
while the service is).

In order to let caller do what it would normally do with
criu-scripts, make criu notify it about scripts. Caller
then do whatever it needs and responds back.
