Fixed NullPointerException during CloneTable due to loadbalancer trying to get the configuration before the namespace is put under the table in zookeeper. Fixed another NullPointerException with the -tn shell option for online, offline, and du. Added -tn option to shell config command. First attempt at adding a randomwalk test for namespaces, fails currently.
fixed a problem with 2 integration tests being in the wrong directory, couldnt compile
Updated ShellServer test with code that didnt fit in the patch correctly
