[tools][fuzz] Retry failed SSH connections from undercoat

In addition to the retry logic added in the previous CL that is specific
to initial instance boot, this CL adds retry behaviour at a lower level
so that it will apply to all SSH commands run against the instance.

The two levels of retry logic remain separated because `start_instance`
needs to handle the edge case where the connection succeeds but the
remote command fails.
