consul package and basic client added (#716)

* this adds a consul package which can be used to fetch a consul binary
* it also adds a `ConsulProcess` helper which can be used to spawn and manage a consul service instance
* zencore dependencies brought across:
   - `except_fmt.h` for easer generation of formatted exception messages
   - `process.h/cpp` changes (adds `Kill` operation and process group support on Windows)
   - `string.h` changes to allow generic use of `WideToUtf8()`
