[2/6] accumulo git commit: ACCUMULO-3475 Remove configError and use
config(String...) retval
ACCUMULO-3475 Remove configError and use config(String...) retval
The return value of config(String...) is ignored, using the
configError member instead. We can get rid of that member and
use the retval instead to denote the same thing.
