Issue Summary

Jira currently has no way of exporting the Custom Fields, their values, and their context. 

Using the UI, the admin will have to search through multiple pages of results and no way to copy the values to quickly view the data. 

Suggested Solution

Add a way to export all the Custom Fields, Custom Field Values, and the context.

This will allow admins to quickly browse a list of the Custom Fields to know their context among other information.
