Comment 14 for bug 1845506

TODO from here:
- Test attaching multiple disks in one XML (hot add) just to be sure
- reword the bad help text in virt-aa-helper
  - split operation modes / general options / file passing
  - add some more words to differ between -f and -F
- In AppArmorSetSecurityImageLabel for the load_profile call switch append to true
   - this is the actual fix for this issue
- AppArmorSetSecurityImageLabel can be simplified by refactoring it to use
  - reload_profile instead of load_profile
  - logic is mostly the same
- Create test builds in PPA
- Test case on test builds
- Upstream the change
- backport Fixes to affected Ubuntu release
