Added a feature to allow get and set of license from Tenable SC

[mark-carey-sap]

Added a feature to allow get and set of license from/to Tenable SC objects. This is used for automation since we install and rehydrate our environments from source periodically.

Description

This is a simple patch to expose licensing functionality for automation. It adds a license API object to the main Tenable SC object and provides a simple get/set method to allow the examination and setting of licenses in a non-GUI way.
