Aleksandr Chesnokov updated IGNITE-26751:
-----------------------------------------
Description:
Save node version to local metastore after each successful start. On startup,
compare current version with saved version. If current version is older than
saved version - crash immediately
An example is given below:
* Start 2.18 -> save 2.18
* Upgrade to 2.19 -> save 2.19
* Node crashes for some reasons
* Try to start 2.18 -> sees saved 2.19 -> crashes because 2.18 < 2.19
It prevents connecting downgraded nodes to updated cluster in Rolling Upgrade
Mode
