so that other features can indicate that they need a storage engine
but do not need to reference a concrete storage engine such as "mmfiles"
or "rocksdb"
database feature now comes first. this ensures that the mmfiles collector thread
(owned by the mmfiles logfile manager) can always access the list of databases,
and that this list is not destroyed while the collector thread is still running.
