Remove default override for config options policy_file

olso.policy 4.5.0[1] changed the config options policy_file
default value to 'policy.yaml', which means it is changed
for all the OpenStack services and they do not need to
override the default anymore.

NOTE: There is no change in behaviour here, oslo.policy provides
the same configuration that services have overridden till now.
