Fix in switchorch: unsupported attribute causes skipping of processin…

…g the rest of configurations (sonic-net#3209)

What I did
Changed it so that if the configuration has an unsupported attribute, it would continue processing the rest of the configuration rather than break out of the loop and end the processing immediately.
Also added syslogs to make it more clear.
