io_fiber/store_snapshot_descriptor now gets the actual number of items
preserved when the log is truncated, fixing extra entries remained after
log snapshot creation. Also removes incorrect check for the number of
truncated items in the
raft_sys_table_storage::store_snapshot_descriptor.
Minor change: Added error_injection test API for changing snapshot thresholds settings.
