Update nova.sh script
Update nova.sh script

This commit updates the nova.sh script.

This script is used to test that the deployed
nova environment actually works.

It also helps complete the configuration of the
deployed nova environemnt so that it is ready to be
used.

It does the following:
  - imports an image to glance
  - creates a private/pub keypair and imports the pub key to nova
  - boots a VM using the created image and keypair.
  - creates ec2 credentials
