Hi Airflowers,

This email calls for a vote to introduce restructure the CLI to use nested
commands instead of flags. The vote will last for at least 1 week (June
18th 12:00 BST), and at least three +1 (binding) votes have been cast.

The original discussion  <
https://lists.apache.org/thread.html/94c97ed621706a2e9130a3550b879a5838c23209f2d6d40f8bb49cd8@%3Cdev.airflow.apache.org%3E>
was positive and the proposed implementation is at
https://github.com/apache/airflow/pull/4821. Since this is a breaking
change it will be for Airflow 2.0.0 only.

An example of the proposed changes to the cli:

- `airflow list_dags` -> `airflow dags list`
- `airflow pools -l` -> `airflow pools list`
- `airflow pools -a` -> `airflow pools add`
- `airflow initdb` -> `airflow db init`

And an example "group" help message:

   usage: airflow db [-h] {init,reset,upgrade} ...

   positional arguments:
     {init,reset,upgrade}
       init                Initialize the metadata database
       reset               Burn down and rebuild the metadata database
       upgrade             Upgrade the metadata database to latest version

   optional arguments:
     -h, --help            show this help message and exit

This is my (binding) +1 vote.

A reminder about binding/non-binding votes: PMC members and Committer's
votes are binding for AIP; other members of the community are encouraged to
vote with a "(non-binding)".

Thanks,
Ash
