This commit refactors the config into a `main.Config` object instead of a global singleton. The `core.Service` is also refactored into the `main` package and individual pieces of the service are wired together by the `pilosa` binary. These two changes are required to begin to decouple packages from one another and allow them to be individually unit tested. Previously most top-level objects in the system could access any other top-level object through the `core.Service` which effectively made `Service` a singleton in the system. Each top-level object now has inline interfaces for their dependencies so that can be set at runtime by the `main` package or can be mocked by a test package.
