2020-03-26nat: transitory timeout for TCP CLOSED stateKlement Sekera1-2/+40

2020-03-13nat: timed out session scavenging upgradeFilip Varga1-67/+128
Patch changes the behavior of session scavenging and fixes multiple nat issues. Allows proper session clearing and removes issue with lingering sessions in session db. Patch also updates and fixes CLI/API calls for better readability of session state metrics. Fixes security issue that would allow attacker to reuse timed out session in both directions (in2out/out2in).

To enable NAT plugin endpoint dependent mode add following to statrup config: nat { endpoint-dependent } Enable endpoint dependent filtering and mapping for all sessions.
