[AIRFLOW-6399] Serialization: DAG access_control field should be decorated field in DAG serialization

[lsimoneau]

This is a modification of #7374 to fix a failing test caused by inconsistent ordering between the serialized DAG and the ground truth DAG.

The _access_control field needs to be defined as a decorated field so the field can be serialized/deserialized incorrectly.

Here are some useful points:

• Pay attention to the quality of your code (flake8, pylint and type annotations). Our pre-commits will help you with that.
• In case of a new feature add useful documentation (in docstrings or in docs/ directory). Adding a new operator? Check this short guide Consider adding an example DAG that shows how users should use it.
• Consider using Breeze environment for testing locally, it’s a heavy docker but it ships with a working Airflow and a lot of integrations.
• Be patient and persistent. It might take some time to get a review or get the final approval from Committers.
• Be sure to read the Airflow Coding style.

Seems like one of the builds timed out on a CLI test? The tests run green in Breeze on my machine so might just need a bump?

[potiuk]

Yeah. Travis got wuiyr unstable those days. I restarted it.

Thanks @lsimoneau and @codenamelxl

@kaxil thanks for that. Can I ask if you expect this to be released in a version before 2.0? We rely on serialisation for some of our cluster monitoring, and are trying to roll out RBAC now but this is a blocker. Otherwise we may try building off a fork for now, but wanted to check with you if there were more bugfix releases coming before 2.0.

Yes this will be included in Airflow 1.10.10 which is expected to be released by early to mid-April (next Month)
