I modified DatabaseConfiguration to ensure the connection is always closed.

> The DatabaseConfiguration class queries each property as it gets the request for each property.  This is 
> nice for ensuring that you're always up to date, but it doesn't give very good performance in enterprise 
> applications, where the database may not be on the same subnet.
> What we need is the ability to hit the database once, get all the keys/values and then serve up 
> "getString" etc. from that cache.
> I'll be opening a separate enhancement to have a generic Reloading Strategy which could then be 
> applied to this caching DatabaseConfiguration approach.
