Java Script Library Support for Policy Condition scripts

To expand on the enhancements in OPENAM-2107 requesting ability to include include javascript libraries to reduce maintenance and utilize standard tools in Policy Condition scripts.

This functionality is currently supported in the XUI feature and in OpenIDM, but not in the Policy Condition scripts. An example of a library we'd like is lodash.js. Also to add the ability to create our custom javascript libs (like av_security.js) and use exports to expose security-based operations that are maintained at the enterprise level instead of replicating the functionality in every script.
