Issue 550: Added support to filter location-based filters further by type.
* core/src/main/java/org/jclouds/providers/Providers.java (boundedByIso3166Code): Added another implementation that takes a type to further filter the results. (collocatedWith): Added another implementation that takes a type to further filter the results. * core/src/test/java/org/jclouds/providers/ProvidersTest.java (testBoundedByIso3166Code, testCollocatedWith): Updated to test the versions that now take a type as an argument.
