Show connector for inbound connection to KSVC from D/DC/KSVC

currently in topology we visualise and support ksvc as subscriber only from could events through EventSources/Channels/Brokers.

But there could be scenario where user want to have connector between D/DC/KSVC to a KSVC just as we have for other workloads

so we are expecting a visual connector from frontend deployment going to ksvc and to db

frontend (deployment) ----> KSVC -----> DB
