Add 'was' operator to issuetype for JQL search

Problem Definition

Based on this document: https://confluence.atlassian.com/jira/advanced-searching-179442050.html#AdvancedSearching-Type

'was' is not a valid operator for issuetype

Suggested Solution

Add 'was' operator for issue type as this would allow reporting on past issue types.

Workaround

Using the the JIRA Suite Utilities plugin it's possible to use the Copy Value From Other Field Post-Function, allowing JIRA to be setup in the following manner:

Remove the Issue Type field from the default screen scheme, disabling users ability to edit an issue type normally.
Add a workflow step to change the issue type.
This step will use the JIRA Suite Utilities post-function to set the old Issue Type in the Custom Field.
