feat: setup volume health monitoring based on lv_attr bits

[jakobmoellerdev]

fix #874

First implementation draft of using Volume Health Monitoring.

TODO:

• E2E Tests
• Unit Tests for various failing health cases
• Integrate https://github.com/kubernetes-csi/external-health-monitor (optional because of kubelet also checking CSINode call)

Im having trouble testing this in an artificial environment. Does someone here have an idea on how to enforce a failure state on one of the volumes?

@jakobmoellerdev
Sorry for my late response. Are you still in trouble?

Does someone here have an idea on how to enforce a failure state on one of the volumes?

Do you mean that you want to have a PV (of Kubernetes) in failure status in test environment?

Hi, yes im still stuck there and am looking for input. I am trying to get a lv into a state that would trigger the Volume Health Monitoring error without other errors such as mounting / deactivation to interfere so this can be properly tested
