Isomorphic cookie API

[charypar]

Similar to the redirect API, we should support a cookie handling API for reading and setting cookies uniformly on both sides of the wire.

Thanks for logging this. Additional things to consider with reading/setting cookies (just in case you hadn't), some cookies maybe only be http ones and secure (i.e. served over https). Not sure if and how this impacts the approach to solving this.

As a side note, being able to inject stuff into app-state before rendering server-side would be quite useful for stuff like loading stuff based on cookie data. Alternatively, giving Arch access to cookie data can also work.

@tabazevedo should be doable in applications start call? Or am I missing something?

[tabazevedo]

@charypar we need the request object from the http server to access cookies (which isnt available in start initialiser as it stands). we're currently doing it via our custom server, but obviously we want to be as seamless as possible.

[charypar]

@tabazevedo I think you'd get arch.cookies function to read cookies, that would do different things based on where you are calling it...

See #53

Since this is still open, I figured I'd mention set-cookie, which does this already and is used at AirBnB (not affiliated).

@chrisvfritz oh, thanks for that. Super useful. Ended up writing my own in a spike i did a little while ago but its probably better to use that, looks great
