Add ability to check an arbitrary Keeper

Official CH changelog text
Add the ability to check an arbitrary Keeper node's stat during the write tx. This can help with ABA problem detection. #87282 (Mikhail Artemenko).
Add the ability to check an arbitrary Keeper node's stat during the write transaction to help detect ABA problems.

Why it matters

The feature aims to solve the ABA problem by enabling validation of a Keeper node's state during write transactions. This ensures higher consistency and reliability when interacting with Keeper nodes by preventing issues caused by state changes that might otherwise be unnoticed.

How to use it

Users can enable this feature by invoking the new capability to check a specific Keeper node's stat within their write transaction logic. This check is integrated into the transaction process to detect any unexpected state changes dynamically.
