(cherry picked from commit cfb7e8186d83e45092f361f9717c9542bfad053b)
The command to set the vpn interface is changed in the rolling release
which is not modified in many configuration examples, corrected syntax
in all pages where it is mentioned
A private key is also needed to finish the ipsec setup which is not mentioned
in the section "Source tunnel from loopbacks/Setting up IPSec". I have added
for reference.
RSA-Keys page was blank, so added the steps to generate and add the keys to
the VPN IPSec config.
Also corrected the IPSec/GRE page where authentication parameter was
missing before remote-id.
