Implements the initial upgrade capability across CMAPI and the CLI, including
repository setup, package operations, environment prechecks, and coordinated
cluster steps with progress reporting.
Details:
- CMAPI upgrade manager:
- Add `cmapi/cmapi_server/managers/upgrade/` modules:
- `repo.py`, `packages.py`, `preinstall.py`, `upgrade.py`, `utils.py` and `__init__.py`
- Extend endpoints and routing to expose upgrade operations and status:
- `cmapi_server/controllers/{endpoints.py, dispatcher.py, api_clients.py}`
- `cmapi_server/managers/{application.py, process.py}`
- Add improved constants and helpers for upgrade flow
- Backup/restore and safety:
- Add `cmapi_server/managers/backup_restore.py`
- Fix pre-upgrade backup regressions (due to `mcs_backup_manager.sh 3.17 changes`)
- Improve cluster version validation; add `ignore_missmatch` override
- CLI enhancements:
- Progress UI and richer feedback (`mcs_cluster_tool/tools_commands.py`, `README.md`, `mcs.1`)
- Add steps to start MDB and start MCS during/after upgrade
- Improved error surfacing for version validation
- Platform and packaging:
- Ubuntu and Rocky Linux support
- RHEL/DNF dry-run support
- Distro detection and platform-dependent logic hardened
- Logging improvements
- Updater service:
- Add `cmapi/updater/cmapi_updater.service.template` and `cmapi_updater.sh` to make CMAPI update itself
- Docs:
- Update mcs cli README and mcs.1 man file
- Add `cmapi/updater/README.md`

Better solution is to use query SELECT @@global.gtid_strict_mode;

But need to investigate how to implement it if no crossengine
