* fix: monitorUpstreamConnectionState CPU consumption
`monitorUpstreamConnectionState()` is a goroutine that listens for GRPC client connection changes using GRPC's `WaitForStateChange` method. `monitorUpstreamConnectionState()` was consuming the a lot of CPU. It was continuously running and not actually waiting for state changes. The `state` for `monitorUpstreamConnectionState()` was not getting correctly updated which caused the loop to continuously run instead of waiting for new state changes.
Update GRPC `WaitForStateChange` method to use the same `state` that gets updated.
