allow module to work without SSL validation and nonprivileged users

Added an insecure option to the client/module to allow for non functional SSL certificates. Updated the module to not use keystone calls that generally require admin privileges if the network is being created for the calling tenant. Also fixed a bug where the error message from the neutron library would not be displayed when listing networks failed.
Merge branch 'quantum_subnet_nonprivileged' into quantum_network_nonprivileged
