   Hi @xiangfu0 Unfortunately, we cannot do this at the moment, because both 
pinot-common and pinot-core define a BasicAuthUtils class with the same name, 
and both classes are used in this method. Supporting this change would require 
merging the two classes. Do you want me to merge these two classes with the 
same name?
