+Subject: apparmor: Fix quieting of audit messages for network mediation

they had been specifically marked as quieted.

+Subject: UBUNTU: SAUCE: apparmor: Add the ability to mediate mount
Add the ability for apparmor to do mediation of mount operations. Mount
rules require an updated apparmor_parser (2.8 series) for policy compilation.
