T8097: strongswan: add CLI for ESN
Add CLI commands:
set vpn ipsec ike-group MyIKEGroup proposal 1 esn ESN-VALUE
set vpn ipsec esp-group MyESPGroup proposal 1 esn ESN-VALUE
Where ESN-VALUE can be one of:
* required: only establish connection using ESN
* optional: try using ESN, but if not available, accept non-ESN
* disabled (default): don't use ESN
StrongSwan 6.0.6 doesn't allow connections between proposal with
'-noesn' and without '-esn'/'-noesn'. To make it work as expected, use
two proposals for 'optional' and 'disabled':
* required: PROPOSAL-esn
* optional: PROPOSAL-esn-noesn,PROPOSAL
* disabled: PROPOSAL-noesn,PROPOSAL
