lib-storage: Index rebuilding (for [sm]dbox) caused it to reset dovecot.index.cache file
Although in some situations this might be wanted, usually it's not needed
and simply makes the performance worse. If caching is explicitly unwanted
the dovecot.index.cache file can be deleted manually for now. Perhaps there
could be a separate doveadm force-resync parameter to do it as well.
