Code Issues Proposed changes

Adding basic connectivity scenario to Neutron

Browse Source 
A Basic scenario:
- Creates an internal network and a subnet
- Creating a key pair
- Creating a router, setting the gateway and adding an
  internal interface
- Lauching an instance with a Nic connected to the internal network
- Adding rules to the tenant's default security group to allow SSH
  and ICMP
- Creating and associating a Floaing IP to the instance
- Checking SSH connectivity to the instance Floating IP address

Scenario Tests
~~~~~~~~~~~~~~
Scenario tests (neutron/tests/tempest/scenario), like API tests, use the
Tempest test infrastructure and have the same requirements. Guidelines for
writing a good scenario test may be found at the Tempest developer guide:
