Reduce logging in scheduler

The logging in the scheduler is what takes most of the time,
once you are doing no DB calls.

This ensures the servicegroup is_up and retry_filter only log
on failures, which is more in line with the other filters.

Using the test "test_performance_check_select_destination"
modifying it to use 200 hosts, the request time went from
70ms to under 10ms.

We could reduce logging further, but this minimal change makes
a massive impact. The next steps would require a config value
to disable all debug logging in the scheduler.
