The local config is intended to be configured per environment. Therefore
it feels awkward to navigate deeply into the structures simply to adjust
a local configuration. Furthermore this change allows me to make an
assumption about the file right in the executed code, so if the file is
not setup properly ansible will fail even before execution!
Here we start to have some delicate secrets in the code. Therefore I
need a vault for ansible. This vault contains the tokens to upload
ssh-keys to github and my lovely gitea server.
Note, that this change also adds a `requirements.yml`, this is necessary
because I use the paramater "api_url" of the github_key resource which
was only added in v11, but the debian ansible was shippped with an older
collection.
