The WNBD adapter may be reset in certain situations (e.g. driver upgrade, MS WHQL tests, etc).

We're going to monitor the WNBD adapter using WMI¹ events, restarting the rbd-wnbd disk mappings whenever necessary. Adapter monitoring can be enabled by passing the --adapter-monitoring-enabled flag to the service.

This feature is optional for the following reasons:

• it's mainly used during development / driver certification
• we had to use a relatively small polling interval, which might imply additional resource usage. WMI quotas also have to be considered.
