Revert "[VOL-4102] Adding exponential backoff to retry reconnection in case of a"

This reverts commit 66fbaf55ddb256bb84be1b907d4f12071bfac052.

Reason for revert: It should not be needed to try to reconnect the stream on a gRPC disconnect as the gRPC should be trying to reconnect under the hood. This needs more investigation but it's breaking the soft-reboot scenario so it's reverted for now.
