Some of the tests waited for excessively long periods of time for changes to propagate. With a one second monitor interval, a sleep of around five seconds should be plenty enough for all monitor related changes to be propagated to all systems.

Reproduce:
|
|
1. connect readconnroute with mysql client
|
|
2. fail the backend server
|
|
3. execute query by using mysql client
|
|
|
|
>> client hangs if write to backend socket doesn't return error (which doesn't happen in many cases)

Added a check for server status before routing the query. Now if the server is down it returns an error.
