To completely disable a cache, either comment it out or remove it from 
the config.  I do not know whether setting the size to 0 will actually 
work or not.

Most changes to solrconfig.xml just require a reload.  I would expect 
any cache configurations to fall into that category.

I don't know anything about the statsCache.  If you don't see it in the 
Plugins/Stats tab, that's probably something that was forgotten, and 
needs to be added to the admin UI.
