Better understand the resources to better use them

A resource quota is allocated to each Nova project.
This determines what can be used to create and manage virtual machine instances.

List of available ressources:

• virtual machine instances
• VCUPs - Virtual Central Processing Unit: processors that are assigned to virtual machines.
• RAM - Random Access Memory
• floating ip adresses : public and routable ip addresses that can be assigned to instances.
• security groups : allows you to define a set of ip filtering rules to limit access to instances from the outside world.
• volumes : storage devices that can be attached to an instance.
• storage of volumes : overall storage capacity for the project.
