Put the support backup Anonymizer into JIRA BTF

Idea taken from here https://confluence.atlassian.com/pages/viewpage.action?pageId=154633652

Support often takes data from customers where there's still a bit of overhead and time involved in getting the data from the customer to a working state in support.

What currently happends:

• Support needs to convince customers that our data anonymizer is safe enough for them to trust (it really isn't)
• Customer follows that guide (sometimes with difficulty, needing more bounces) and attaches the backup
• Support needs to restore the backup locally
  • Turn off emailing
  • Worry about CDATA cleaning
  • Change the passwords to sphere
  • Change any cwd_directory info disabling everything but local directory
  • Worry about any remote groups and make them local groups also
• Then we can log in and start troubleshooting

Request
It would be great if JIRA BTF's internal backup facility could just do this, use joost.jar to anonymise a backup on request and send it off to a support issue all in one go - just tick a box "anomonize backup for Atlassian support" and there it is.
