Disable valcache for transactor
Given that the transactor will run on top of SQLite, its disk IO for reads when
accessing the valcache is replaced by SQLite itself. In this topology, we don't
get any upside on enabling valcache for the transactor, and even loose
performance due to the cache IO competing with the database IO.
Peers can enable the valcache for themselves, if desired.
