clients close the stream and any connection when they are done with it
servers close the stream after a 1 minute timeout
proxy JoinService gRPC server closes idle connections with no RPC calls after 10 seconds
This adds proxy peering support. A configurable setting that allows for agents
to connect to a subset of proxies and be reachable through any proxy in the
cluster. This is achieved by creating grpc connections between each proxy
server. Client connections can then be passed between proxies to the desired
agent.
