Code Issues Proposed changes

Reedip Banerjee 82c9ab771b Improve neutron-client error message output 
In case a user provides incorrect input, the NOVA CLIs provide
information regarding usage of the NOVA help CLI. This is useful
for new users. Similar information has been updated in the neutron
CLIs as well.
