In an effort to standardize policy and authentication values oslo.context has new features such as from_environ which constructs a standard oslo.context object from the environment variables created by auth_token middleware and to_policy_values which emit a standard credentials target for writing common policy files across services. Use these standard functions when dealing with contexts and policy in glance. Closes-Bug: #1602081 Change-Id: I40582cb34818b980d6c6914b2c9346a17a0ed489
