[doc] Update releasing documentation

At the moment our documentation does not contain any steps that
should be made to create EOL or EM releases. With that existing
releasing documentation is slightly outdated and not fully reflect
actions that should be made during periodic work.

Please note, that only collections with type `git` are supported.
Ones, that are installed from Ansible Galaxy should be bumped manually.

Trasition releases to Extended Maintenance
------------------------------------------
With migrating a release to `Extended Maintenance`_ (EM) status no future
releases of the release are possible. With that, a new tag <release>-em is
created and it must be based on the latest numeric release.
To transition a release to Extended Maintenance we need to:
* Wait until all upstream repositories will transition to EM
* Update OpenStack-Ansible roles normally
* Update ``<service>_git_install_branch`` to be ``<release>-em`` instead of
the SHA.
* Propose a new numeric release to ``openstack/releases`` repository
* Propose to create a ``<release>-em`` tag with the same SHA as previous
numeric release has.
* Once EM tag is created, switch ``version`` field in
ansible-role-requirements.yml to track ``stable/<release>``.
* Update ``index.rst`` for master branch to reflect support status of the
release

Trasition releases to End Of Life
---------------------------------
With releases reaching `End Of Life`_ (EOL), a new tag ``<release>-eol`` is
created, after which branch will be deleted. Projects are free to EOL their
branches anytime, after coordinated migration to EM is completed. Due to this
we don't track ``stable/<release>`` branch for upstream services for EM, but
only for our roles. At the same time there is a coordinated deadline, when all
projects must EOL their old branches.
To transition a release to End Of Life we need to:
* Create a <release>-eol tag for OpenStack-Ansible Roles
* Switch ansible-role-requirements.yml ``version`` field to <release>-eol tag
from stable/<release> branch.
* Wait for all projects to EOL
* Update ``<service>_git_install_branch`` variables to use <release>-eol tag
instead of SHAs.
* Create a <release>-eol tag for OpenStack-Ansible repository
* Update release support status in index.rst on the master branch.

* Revert changes made to ansible-role-requirements.yml and

Update upstream SHAs.
* Reflect changes in documentation
* Create a patch to openstack-manuals and uncomment OpenStack-Ansible in
`www/project-data/<release>.yaml`.
* Update index page on master to mention release date of recently
released version as well as set its status to Maintained. With that
also add a new release that we are about to start working on.
* Update index page on stable branch to mention only the release in topic
rather all historical releases as well. Historical data should be
present only on master branch.
* Update upgrade scripts and documentation to keep track on supported
upgrade paths:
* For SLURP releases, define ``previous_slurp_name`` in
doc/source/conf.py. For non-SLURP - set it to ``False``.
* Update ``previous_series_name`` and ``current_series_name`` in
doc/source/conf.py and deploy-guide/source/conf.py
* Update ``UPGRADE_SOURCE_RELEASE`` in scripts/gate-check-commit.sh
* Update ``SUPPORTED_SOURCE_SERIES`` and ``TARGET_SERIES`` in
scripts/run-upgrade.sh. Also don't forget to cleanup irrelevant
upgrade scripts.
* Add/remove required for SLURP upgrade jobs. ACTION for such jobs
should be defined as ``upgrade_<release>``.
