Eco-CI is currently not senstive for the runner size

[ArneTR]

At the moment we just use the values for the smalles linux runner:

• https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners/about-github-hosted-runners#standard-github-hosted-runners-for-public-repositories

However large runners also do exit and they have different specs:

• https://docs.github.com/en/actions/using-github-hosted-runners/about-larger-runners/about-larger-runners

At the moment GitHub provides no easy mechanism to find out on which runner size one is provisioned.

We need a mechanism to feed these values in manually.

An alternative would be to use the --auto detect mechanism of cloud-energy and write all splitting factors down manually
