[bug] generation_info cant be cached per replica
This info can be changed by another syncing replica and would not
reflect real database generation. That would be ok inside of the same
sync, but can cause trouble on concurrent syncs.
The other calls are ok, since they hold info that doesnt change during
concurrent syncs or are only read/write by the replica syncing. A global
cache could fit better this removed case, but for now let's stay on the
safe side.
