NAT44: add support for session timeout (VPP-1272)
NAT44 (vanilla/simple and endpoint-dependent mode) now lazily delete expired sessions. When inserting to session lookup hash and bucket is full, expired session is overwritten. Change-Id: Ib1b34959f60f0ca4f5b13525b1d41dd2f992288d Signed-off-by: Matus Fabian <matfabia@cisco.com>
