Get connected agents by a list of agent or project
Closes New API: get connected agents by a list of agen... (#158 - closed).
This MR adds new arguments to GetConnectedAgents
gRPC method. This change will be able to decrease the number of gRPC requests that KAS makes because KAS can request the agents info for multiple agent IDs or project IDs in the single request.
