Adds default policy rules for resources which are limited to admin

[huangtianhua]

Heat has several resources which are limited to being used by administrators only by default policy rule. Such as:
OS::Cinder::EncryptedVolumeType
OS::Cinder::VolumeType
OS::Neutron::QoSPolicy
OS::Neutron::QoSBandwidthLimitRule

This change will add the default policy rules for these resources to tell user the forbidden reason in the early time instead of in creating progress.
