* Remove __main__ references and create a top-level config module
* Move conf module into separate standalone package
* Deprecate install_imports.py script
* Rename root package to kube_hunter
The previous src root package name was too generic and not unique,
so it can be used as external name.
Change `src` to `kube_hunter` so it can be referenced in a clear way.
Addtional changes made on the way:
* Make imports absolute
* Formatting
Relates to #185
* remove todos
