The terraform-state can be stored in backblaze b2 with some
configurations. This changes does exactly this. Note, that this requires
the special env-variables `AWS_SECRET_ACCESS_KEY` and
`AWS_ACCESS_KEY_ID` which are normally part of the AWS-setup. To be able
to use AWS and this setup in parallel I use dotenv to maintain the
variables in the special file `.envrc`.

It simply doesn't make sense to split the installation of the
kubernetes-cluster from the provisioning of foundational services.
Therefore I drop the idea to organise these services in another
terraform-setup and instead ensure their presence with ansible, as it's
already responsible for setting up the cluster and keep it up-to.date.
