Allow DB config to be reloaded on the fly
This introduces $wgLBFactoryConf['configCallback'] which can be set to a
function that returns updates to be applied to $wgLBFactoryConf. The new
method LBFactory::autoreConfigure() can be called to check the callabck
and, if the config changed, reconfigure all existing LoadBalancers.
Reconfiguring the LoadBalancers causes all open connections to be
invalidated; however, any DBConnRef instances will remain valid and will
acquire a fresh connection from the LoadBalancer automatically when
appropriate.
As a proof of concept, this patch adds support for config reloding
into WikiExporter.
