> ACCUMULO-4458 mitigated some contention on the Hadoop Configuration instance backing the XML configs read for SiteConfiguration, but at the expense of maintaining some more information about how we use properties in critical code paths.
> For this improvement, we should avoid keeping around the Configuration instance at all after reading values out of it. This will require some amount of refactoring for those cases where tests seek to set configuration values on the SiteConfiguration object after instantiation.
