Worker log level is not based on what is set in opcfg

[stephanievu]

What I Did
I turned on opscfg.default.server.log_level->5

What I Expected
Worker's activity should be logged as 'verbose' mode

What I Saw Instead
Workers activity was still logged with 'warning' mode. Looks like log_level config in opscfg is ignored, Worker codes use log_level in hera.txt
