What you're essentially asking for (especially with the toml like configuration) is SLURM + GPU cluster.
SLURM does that wrapping for you, where you essentially just point to the file that you want to run, along with some high level GPU and CPU resource allocation tags, and it just schedules and runs it for you.
I have seen some people trying to run GCP (lol) with SLURM, and wouldn't be surprised if it is possible with AWS/Lambda or any of the other cluster service providers (Cluster-as-a-service, CLaaS?).

Just through one Google search, looks like its definitely possible with AWS: https://docs.aws.amazon.com/parallelcluster/latest/ug/slurm-...
