[apparmor] [PATCH 0/2] Add JSON ability for changes

[Goldwyn Rodrigues]

This series adds JSON for communicating the temporary diff file
between the old and new profiles.

I had to move code from aa.py to ui.py so that we don't have
circular dependency in imports. Performed some cleanup there.

In order to write a profile, I had to use the following
patch for mount, pivot_root and unix on my 4.14.0-rc5 kernel.
