Alert when the VWD session host status becomes "unavailable"
Currently, there is no way to notify the VWD session hosts that their status has changed.
There is a diagnostic data, but it only detects a failed session host connection.
Customers want to be notified when the session hosts status transitions, not when the connection fails.
The reason for this is that customer want to deal with any event that makes a session host unavailable as soon as possible.
