1. We register both apirule and rule into enforcer, so we can keep
the rule in the check_str
2. We re-generate all the services' policy, we just use the original
policy of them. If users want to change, they can change them by
themselves.
3. Adjust the post_install.sh, we install the service packages with
dependencies.
4. Split the ironic and ironic_inspector policy, they can not be in
the same policy file.
