Support health monitoring with external-health-monitor-controller

[maxenglander]

Is your feature request related to a problem? Please describe.

AWS exposes volume status via describe-volume-status. AFAIK this (and the UI) is the only way to observe volume impaired status.

The aws-ebs-csi-driver seems like a good place to collect and expose this information. @ConnorJC3 already made a PR to do this but it went stale and was closed. Would love to see that work revived and merged:

• Volume Health Monitoring #1495

Describe the solution you'd like in detail

I think that #1495 does everything I need. An additional nice feature would be the option to enable monitoring on a per-volume basis. This would potentially reduce the expense associated with the additional API calls, and allow the enable volume monitoring only where volume health is critical.
