Kubeadm cluster support

[pabloopez]

Add support to deploy as an option the Sysdig Agent with Helm in our k8s-based Instruqt environments.

This is required for Compliance training, support to use KSPM in our k3s cluster is not guaranteed, I prefer to run the new labs for compliance directly in our kubeadmin k8s cluster and avoid any issue due to not being compatible.

I see a request for me to review, but this is still in draft. Should I review it?

[pabloopez]

No, is a draft. But yes, I'll ask you to review when this is ready.

Testing this now, looks like it works fine:

sysdig-agent   sysdig-agent-22wv5                            1/1     Running   0          2m38s
sysdig-agent   sysdig-agent-5q26m                            1/1     Running   0          2m38s
sysdig-agent   sysdig-agent-kspmcollector-858994c89d-wjbrw   1/1     Running   0          2m38s
sysdig-agent   sysdig-agent-node-analyzer-2xt7z              4/4     Running   0          2m38s
sysdig-agent   sysdig-agent-node-analyzer-rknrf              4/4     Running   0          2m38s

And logs for the kspm component:
