Allow users to hide Issue ID and Parent ID fields while including issue key when exporting filter to CSV

When Exporting a search or filter to CSV, including the "Key" field in the export will also include the Issue ID and the Parent ID.

Because the issue ID and Parent ID are not always needed or useful when using CSV exports for reporting purposes, and it can cause issues when lining up data in certain environments, it would be useful if the option to specify that it not be included in the CSV is included.

To this end, I would like to propose that a third export to CSV option be created to allow for explicit selection of which fields to export rather than rely on the current view as this is not immediately apparent to users what fields they have selected as it is common for them not to take an active role in selecting specific values.
