HONEYCOMB-358 - Generate guice to yang modules index
Generates two descriptor files
yang-modules-binding/yang-modules - List of Yang modules by project(classpath + deps)
yang-mapping/FULL_PROJECT_NAME-yang-modules-index - Index from Guice modules to Yang modules
that are used by respective Guice module
These files are included in jar files and distribution resources
