I also plan to dockerize osm data and natural earth but just wanted to get the review process started.

@gregtzar I would like to move this work to the subfolder imposm. The plan with this repo is to also provide scripts for working with other OSM import (see #50 and #51). Each of these could have an associated DockerFile, scripts, and tegola configs.

@ARolek I renamed the osm scripts to include imposm in the name, as well as some other changes. My thinking is that this structure is nice and simple, flat, and explicit, and it doesn't prohibit us from moving to a more complex structure in the future as we grow the scripts.
