ipsec: T5043: Rewritten and fixed 'reset vpn' commands

1. Rewritten CLI of 'reset vpn' commands.
2. Created 'reset vpn ipsec remote-access' commands to reset
   RA IKEv2 session.
3. Created 'reset vpn ipsec site-to-site all' command to reset all
   configured IPSec site-to-site peers sessions.
4. Rewritten 'reset vpn l2t|pptp|sstp' commands to
   new opmode style.
