Check actor type stuff

[SeanMcOwen]

For the actor type we have:

message Actor {
ActorType actor_type = 1;
string address = 2;
string public_key = 3;
repeated string chains = 4; // NB: Not applicable Validator actors
// proto-gen-c does not support go_name at the time of writing resulting
// in the output go field being snakeCase: ServiceUrl (golang/protobuf#555)
string service_url = 5; // Not applicable to Application actors
string staked_amount = 6;
int64 paused_height = 7; // TECHDEBT: Revisit this parameter and see if it can be removed for simplification purposes.
int64 unstaking_height = 8; // TECHDEBT: Revisit this parameter and see if it can be removed for simplification purposes.
string output = 9; // TECHDEBT: Revisit custodial / non-custodial flows (e.g. what if we want multiple outputs for business purposes)
}

Do we want to use this is a base class for other instantiated entities?
