Beats starting kit

@mrkschan I think as soon as version 1.0 is out this is definitively something we should discuss. As @urso mentioned currently topbeat is a good project to clone and then start with your own implementation.

In the end all beats should have the same Makefile, config structure, .gitignore file etc or at least share the same commands. As soon as we have it unified in our existing beats, creating the template / repo should be easy.

@mrkschan As you created already more then one beat it is definitively good to hear from your side what would help you most to speed up and simplify the creation of new beats.
