ipsec: T4118: Change vpn ipsec syntax for IKE ESP and peer
Migration and Change boolean nodes "enable/disable" to disable-xxxx, enable-xxxx and just xxx for VPN IPsec configurations - IKE changes: - replace 'ipsec ike-group <tag> mobike disable' => 'ipsec ike-group <tag> disable-mobike' - replace 'ipsec ike-group <tag> ikev2-reauth yes|no' => 'ipsec ike-group <tag> ikev2-reauth' - ESP changes: - replace 'ipsec esp-group <tag> compression enable' => 'ipsec esp-group <tag> compression' - PEER changes: - replace: 'peer <tag> id xxx' => 'peer <tag> local-id xxx' - replace: 'peer <tag> force-encapsulation enable' => 'peer <tag> force-udp-encapsulation' - add option: 'peer <tag> remote-address x.x.x.x' Add 'peer <name> remote-address <name>' via migration script
