The Djblets Integration definition of get_configs allows filtering by
arbitrary key value pairs. However, the Reivew Board version only allows
filtering by LocalSite, so this prevents filtering via integration ID
if only one configuration is required. This has been modified to allow
arbitrary key value pairs for filtering, which will be passed along to
the base class.
