Description
The scheduler filters the existing hosts to get the ones with a status less than 3, including the ones in INIT or MONITORING state.
A Host in MONITORING state may be chosen to deploy a VM if there is old monitoring data in it, but the host may be unreachable and end in ERROR state.

The previous commit didn't solve the issue, because a host in MONITORED state changes periodically to MONITORING in each monitoring cycle. With a small monitoring timer, the scheduler couldn't find any host in MONITORED.
We will have to implement one of the following options:
- Automatically disable a Host after N unsuccessful monitor events.
- Introduce a new state, to differentiate a host being monitored to refresh its info (valid candidate for deployment), or to recover from an ERROR state.
