To include the custom_cartridge library

[sweta-singh]

Here we have created a new job to include the custom_cartridge_librarary when we load_platform. A new Job is created : Setup_Custom_Cartridge_Library which will be loaded when we run load_platform and the library components would be imported from here - https://github.com/RobertNorthard/adop-dsl-custom-cartridge-properties.git will be placed in jenkins_home/userContent. We would need to modify the cartridge with cartridgeProperties.getProperty to consume the library. See example here - https://github.com/RobertNorthard/adop-cartridge-skeleton
