Title: Fix source cache key generation

This branch fixes cache key generation for `tilelive-mapnik` source objects. Currently the cache key cannot be fully determined by a request alone and requires loading of the project to determine the `scale` and `metatile` values.

Reduces # of project loads as well as localization/carto compiles on tile requests.
