Pivot: make Rook work with Pedestal

[hlship]

I think the core concept of Rook: expose namespaces as endpoints, combined with its secondary feature: do something sensible with endpoint function parameters, is very powerful.

I think Rook may be better off as an alternate dispatch table generator for Pedestal.

More thoughts on this as I dig down.

Could go from current Rook stuff, with minor changes, to the Pedestal table or terse format. Terse might be better, as that's already hierarchical. Route names could be keyword-ized qualified symbol names for functions.
