Hello,,

The [new Celery 5.0](https://docs.celeryproject.org/en/stable/whatsnew-5.0.html) has been released and we may consider migrating to this version. I don't know if it has to happen now, if we should wait for version 5.1 or do it now. I am creating this ticket to track this version.

To process this issue, we should consider the consequences of this update, update the CLI calls, update API calls, and test these versions thoroughly.

@auvipy Can you tell a little more about this release? Is this release stable enough to update our project to these versions?  What consequences could this update have?

    Adds provider packages as requirements to extra. This is used to add provider packages as requirements
    to the "bulk" kind of extras. Those bulk extras do not have the detailed 'extra' requirements as
    initial values, so instead of replacing them (see previous function) we can extend them.

    In case of regular installation (providers installed from packages), we should add extra dependencies to
    Airflow - to get the providers automatically installed when those extras are installed.
    For providers installed from sources we skip that step. That helps to test and install airflow with
    all packages in CI - for example when new providers are added, otherwise the installation would fail
    as the new provider is not yet in PyPI.
