DO NOT MERGE Apply a maximum char count to the load label api 

The system is overwhelmed by an enormous label string returned by
the load label api. This cl truncates the label string if it exceeds
the maximum safe length.

Also update the max safe label length to 1000 characters, which is
enough.
