As an application, Xray should provide admins with per project custom field clearance and recalculation

Xray should provide Jira admins with a per project ability to: 

• Run the "Clear all Values" from the Integrity Checker
• Run  the "Recalculate Requirement Status" 

This greatly helps in scenarios of a problem with statuses not showing properly and the environment being too big, since clearing and recalculation may take too long.
