Apparmor profile for FRR daemons

[jslarraz]

Hi folks,

I started to work on an apparmor profile for the daemons included in the FRR suite. The apparmor upstream made a couple of suggestions while reviewing those profiles. The path used to store crash logs could possibly be a source of troubles, considering that frr is hardcoded and the pid guessable (and in worst case, the number of possible pids is not that big). They recommended to use a mktemp-generated name or move to a directory that is not world-writable.

I would also very much appreciate if someone could take a look to the apparmor profiles and/or test them trying to identify any potentially missing directory.

Thanks,
Jorge
