dtls: Hibernation and retransmit timers
Change retransmissions timers to use gen_statem state timeouts. We do
not need a retransmission timer in the state connection as data traffic in
DTLS over UDP is not retransmitted. If the last flight before
transitioning into connection is lost, it will be resent when the peer
resends its last flight. This will also make hibernation testing more
straight forward.
We need more adjustments later to handle a reliable DTLS transport
such as SCTP.
