Make this cookbook more flexible
This cookbook is nice for GitLab Inc but if we want to make it more robust so everyone can use it it will need some more love. gitlab-See: org/cookbook-omnibus-gitlab#20
The issue for example is that we have a lot of munin recipes which don't really belong here but rather in a separate (wrapper cookbook).
@dblessing Can you note down all the pain points of this cookbook that made you create the gitlab_omnibus
cookbook so we can see what we can do to improve this?
