  1. fix(Raft): Detect network partition when streaming 

    When streaming raft messages in k8s cluster, we don't seem to get an
error if the send didn't succeed. The packets get queued up, but don't
fail and don't get sent. This causes a long re-election process.

This PR periodically tries to send a message to the destination node via
IsPeer, so it has another way to test the connection. If that fails, the
streaming fails too, and the node is marked as unreachable.
