client: retry RPC call when no server is available (#15140) When a Nomad service starts it tries to establish a connection with servers, but it also runs alloc runners to manage whatever allocations it needs to run. The alloc runner will invoke several hooks to perform actions, with some of them requiring access to the Nomad servers, such as Native Service Discovery Registration. If the alloc runner starts before a connection is established the alloc runner will fail, causing the allocation to be shutdown. This is particularly problematic for disconnected allocations that are reconnecting, as they may fail as soon as the client reconnects. This commit changes the RPC request logic to retry it, using the existing retry mechanism, if there are no servers available.
