device.is_visible_to was called for all devices which generated
approx. num_of_devices * num_of_devices_of_specific_device_type
queries before filtering out the RETIRED devices.
Currently on production that's approx. 100,000 queries per
all_devices api call.
This patch also reduces the number of queries to the device_type
and test_job table for each device.
