ip_hash in active_active nginx setup

[s_n]

Hi,

based on your information we implemented the described setup and did not
encounter any stickiness problems so far. 

Cutting out F5 is sadly a decision that is not under my control. I agree
that it would be a simpler setup with just nginx loadbalancing.

Thanks all.
