Open Stack

At the moment we mention the following minimum requirements for a
proof-of-concept environment in chapter 2 (basic environment):

---snip---
Controller Node: 1 processor, 2 GB memory, and 5 GB storage

Network Node: 1 processor, 512 MB memory, and 5 GB storage

Compute Node: 1 processor, 2 GB memory, and 10 GB storage
---snap---

Does this really work? Has anybody tried to run a network node with only
512 MByte memory? Or a controller node with RabbitMQ, MySQL, MongoDB and
a lot of OpenStack services with 1 VCPU and 2 GByte memory?

I would propose to increase the minimum requirements:

Controller Node: 4 processors, 8 GB memory, and 15 GB storage
Network Node: 2 processors, 4 MB memory, and 10 GB storage
Compute Node: 2 processors, 4 GB memory, and 20 GB storage
