Description

I have noticed that for some commands, there is an option to get the output in json or yaml (as described in this PR from 2020 #12699).

However, there are still some commands that do not support the --output argument, most notable one is the dags trigger.

When triggering a dag, it is crucial to get the run_id that has been triggered, so the triggered dag run can be monitored by the calling party. However, the output from this command is hard to parse without resorting to (gasp!) regex:

[2023-01-26 11:03:41,038] {{__init__.py:42}} INFO - Loaded API auth backend: airflow.api.auth.backend.session
Created <DagRun sample_dag @ 2023-01-26T11:03:41+00:00: manual__2023-01-26T11:03:41+00:00, state:queued, queued_at: 2023-01-26 11:03:41.412394+00:00. externally triggered: True>

As you can see, extracting the run_id manual__2023-01-26T11:03:41+00:00 is not easy from the above output.

For what I see in the code, the ARG_OUTPUT is not added to dag_trigger command.

Use case/motivation

At my company we want to be able to trigger dags from another airflow environment (mwaa) and be able to wait for its completion before proceeding with the calling DAG.
