Switch to load wsdl and schema files from multiple jars

[Hanumesh96]

Currently, WSDL and schema files are only being loaded from the JAR file which has the 'WEB-INF/wsdl' directory and is located first in the classpath. Other JAR files containing 'WEB-INF/wsdl/<WSDL_and_schema_files>' are being ignored.

A custom switch needs to be implemented to enable reading of WSDL and schema files from other JAR files in the classpath. This enhancement will be helpful to support customization.
