Registers in-code the last remaining policy rules. Adds missing 'discoverable' rules. Without them, the extension_info API can fail, as it tries to check the os_compute_api:os_server_tags:discoverable rule. As it wasn't previously registered, when listing the available extensions, an exception of type PolicyNotRegistered is encountered. In order to validate this, functional/api_sample_tests/test_extension_info.py now runs without mocking policy.authorize. Switches extension_info to context.can. Switches nova.cells.filters to context.can. Switches network.neutronv2.api to context.can. Removes the rest of the entries in etc/policy.json. Removes DefaultPolicyTestCase, as it tests the default policy rule, which is not registered. Removes rules from fake_policy.py that brings no value, that are the same as the default values. Removes extensions authorizer factories. Removes nova.policy.enforce. Change-Id: Ie7771768f4f3efe0edc787c12f297aa93d533d7e Partially-Implements: bp policy-in-code
