Passing our own ssh key for the deployment is unclear
In https://api.grid5000.fr/doc/4.0/reference/spec.html#deployments-api one should pass ssh_authorized_keys
but it doesn't work.
A key
must be passed like in https://gitlab.inria.fr/discovery/enoslib/blob/6f3b43c2b8ddc4b9dff4d5296d9aa3f2d97f4382/enoslib/infra/enos_g5k/g5k_api_utils.py#L465-466
We should document this.
