Minor but important corrections.

Hello,


As you know, some of the OpenStack projects were marked inactive during this cycle.
There are still on-going discussions but from my view these are very likely excluded from
the upcoming 2024.1 release and it's unclear yet if any of these projects will be kept.

Currently heat provides features integrated with some of the inactive projects (Monasca,
Sahara and Senlin), and we have to decide how we deal with these features[1].

The main concern is that we can't maintain the features for the inactive projects, and IMO
we should retire these features if these inactive projects are abandoned or are no longer
maintained in the consistent way with the other active projects.

Based on the current situation, I'd propose the following steps for upcoming cycles.

 - Deprecate the features dependent on inactive projects in 2023.2 release
  - Note that we have to remove these features directly during this cycle in case any problems
    related to these project block the upcoming heat release.

 - Deprecate the features dependent on inactive projects in 2024.1 release

 - Remove these features in 2024.1 release unless we are sure that these projects are kept
   maintained as active projects in the openstack namespace, with following the global
   release cycle.

 - Remove these features in 2024.2 release ...

Please let me know if you have any concern about the proposed plan. If I hear no objections
then I'll propose patches for deprecation.

Thank you,
Takashi Kajinami

I've submitted a series of patches to remove these features and these would give a clear view
about the features affected.
