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
