Burak Yucesoy cfe588555a Do not crash if the monitor database is not available
While monitoring database is important, it isn't critical for the entire system
to function. Even the monitor itself can continue to work in degraded mode. So,
if the monitoring database is not available, we should not crash the entire
system. This commit catches Sequel::DatabaseConnectionError that can be raised
while trying to connect to the monitoring database and logs an error message.
