It is not a good idea to have a top-level "tools" namespace, this name is too generic and already taken in PyPi (see https://pypi.python.org/pypi/tools). This patch moves python_nsxadmin to the vmware_nsx.tools namespace, adjusting all imports and making sure setup.cfg is adapted accordingly. Change-Id: I75922db2010194fe59db424cc4615c7ba57c1b81
