Title: Adding keyname when creating server and some floating IPs related methods 

Based on the official python nova client, I added several stuff to the nova provider:

## Server creation
- Specify the security group name (in CreateServerOptions) when creating the server. This is useful since it seems that there is no method in the API to add it later...

## Floating IP
cf http://wiki.openstack.org/os_api_floating_ip

- Get Floating IPs
- List Floating IPs
- Add Floating IP to server
