Gerrit assigns a unique cookie to each browser, that cookie matches
to a record in our web_sessions cache, and the record tells us the
identity of the user. That cache was in memory, which is fine for
single server setups. In order to allow multi-server setups, that
cache needs to be in a DB that all servers can talk to. I added a
DB table that holds these sessions, and is backed up by an
in-memory cache on each JVM. The Schema is still Schema_100, since
nobody is using Schema_100 yet anyway.
