prepare-tool: install tool base deps as root

[viceice]

Add a prepare-tool to install all required distro base dependencies (apt).

@Chumper i think this has high priority, so we can dynamic install for tools like python, dotnet ...

[viceice]

They depends on some libraries which are installed via apt

I am not exactly sure, that the prepare-tool should do.
Are you talking about a new script, that will install e.g. bazaar for golang in the image, so that go can be installed at runtime?

In that case would you do it similar to the installation of tools?
That we have a prepare folder with scripts for each tool that installs certain apt packages?
Or would you rather put that into one prepare-tool file that will do this for all tools?

closing, as it's now implemented and working for erlang
