[apparmor] [patch] Add --no-reload parameter to minitools

[Christian Boltz]

Hello,

this patch adds a --no-reload parameter to aa-audit, aa-complain, 
aa-disable and aa-enforce. This makes it possible to change the 
profile flags without reloading the profile.

Also change tools.py to honor the --no-reload parameter.

References: https://bugs.launchpad.net/apparmor/+bug/1458480


I propose this patch for trunk and 2.9.
