When DAG serialization is enabled, if any DAG contain field: "access_control":
- Scheduler will fail to schedule all jobs.
- Webserver cannot browse those DAG with "access_control"
ValidationError: Additional properties are not allowed ('_access_control' was unexpected)
Failed validating u'additionalProperties' in schema[u'allOf'][u'properties'][u'dag']
Reason: https://github.com/apache/airflow/blob/1.10.7/airflow/serialization/schema.json does not have access_control as a whitelisted field.
AIRFLOW-6425 added '_access_control' to JSON schema but does not define it as decorated_fields making the field to serialized/deserialized incorrectly.
