New generate-dc-config target, rm QUICKSTART_MIN/MAX_ZOOM (#915)

Browse Source 
* Set `MAX_ZOOM` to 7 by default.
* Remove `QUICKSTART_MIN/MAX_ZOOM` - unneeded complexity with two env vars. We can just use `MIN_ZOOM` and `MAX_ZOOM`. See also #261
* Generate dc-config yaml file with a new `make generate-dc-config` step. It will compute BBOX based on the downloaded data file. This step is not needed for planet generation.
* Generate Imposm replication file only when `DIFF_MODE` is `true`. Not needed otherwise. If the data source does not support it, it will throw an error.

Now you are ready to **generate the vector tiles**. Using environment variables
you can limit the bounding box and zoom levels of what you want to generate (`docker-compose.yml`).
Now you are ready to **generate the vector tiles**. By default, `./.env` specifies the entire planet BBOX for zooms 0-7, but running `generate-dc-config` will analyze the data file and set the `BBOX` param to limit tile generation. It will also modify `MIN_ZOOM` and `MAX_ZOOM` values based on the .env, but can be changed.
