Hi there, when I was reading the code of the function

private KubernetesInternalRuntime getKubernetesInternalRuntime(String workspaceId) throws InfrastructureException

in [InconsistentRuntimesDetector.java](https://github.com/eclipse/che/blob/ca780d05e5a3b58dea172268d3752911831e1d7c/infrastructures/kubernetes/src/main/java/org/eclipse/che/workspace/infrastructure/kubernetes/Inconsis

I reinstalled a k3s cluster built with --no-extras and added `--k3s-extra-args="--flannel-backend=host-gw". The cluster failed to start.

I logged in and saw that the output of ps showed the following:

14760 ?        Ssl    0:40 /usr/local/bin/k3s server --cluster-init --tls-san 10.68.0.63 --flannel-backend=host-gw--n

I hope the official can add a new command to automatically generate RESTful API
