Allow switches to be be bound to sites

[kitsunde]

We have several multi-tennant sites and currently we're doing something pretty awkward with waffle where we postfix the site like (feature_video_sg, feature_video_nz) and then do an awkward lookup.

What about a site condition, where you turn a switch on only for specific sites?

Also I presume you're talking about Django's Site framework

[kitsunde]

Yeah we're using the standard Django Site framework. Ideally we would bind the switches m2m to the sites.Site model.

You should be able to create a ConditionSet based on RequestConditionSet that does this.

See IPAddressConditionSet for a sample implementation that looks at the IP of the request - you could easily adapt it to look at request.get_current_site(). IPAddressConditionSetTests are also a pretty good guide on how to test.

If you start and open a PR I'll help with code review and completing anything that turns out to be difficult. Of course you can implement it in your own project's code base right now if you need it right now :)
