Too many 'Enforcing rule' logged on the gate

[Attila Fazekas]

After #1356679 the debug logging became too verbose.
Logging the policy rule checking is useful when you are editing the policy.json, but for general usage it is too verbose.

$ wget http://logs.openstack.org/53/130753/1/check/check-tempest-dsvm-neutron-full/4ad9772/logs/screen-q-svc.txt.gz
$ wc -l screen-q-svc.txt.gz
94283 screen-q-svc.txt.gz
$ grep 'Enforcing rule' screen-q-svc.txt.gz | wc -l
25320

26.85% of log lines contains the 'Enforcing rule'.

These 'Enforcing rule' log messages should be disabled by default (even with debug=True).

Note:
Maybe 'default_log_levels' can be used for make it less verbose by default.
