Feature request: set $Roboo_challenge_hash_input

[Valentyn Rosavitskyi]

Hello,
As I saw in sources cookie value is based on $remote_addr only.
Can we get "set $Roboo_challenge_hash_input" for prevent issues behind NAT users (actually we already have client with similar issues but now Im not sured abut this).
In perl Roboo we using next:

set $Roboo_challenge_hash_input $remote_addr$http_user_agent;
