Porting of changes #2200
What I did
Fixed config reload when timer based delayed services are disabled. When they are disabled, the property property=LastTriggerUSecMonotonic returns "0". This will cause config reload to fail even though all enabled services are up.
How I did it
Fixed the delayed services logic to check if the services are enabled before getting the property LastTriggerUSecMonotonic . Additionally fixed the return codes when config reload fails due to system checks
How to verify it
Added UT to verify it. Modified sonic-mgmt tests to verify it additionally.
