Meg McRoberts 02d728fe72 Nodes and roles -- terminology articles 
Create/improve articles for Nodes, Roles, plus one for each
Role that Fuel recognizes.

We have requests for more detailed information about how Fuel
manages nodes and we also have requests for more accessible
information about which roles can and cannot be combined. This
CR does not completely solve the second request but it's a start.

Add ref-arch/logical-setup/0800-node-internals article to give
detailed information about the information Nailgun stores for nodes.

Added tags to ref-arch/logical-setup files so they can be xref'ed

A couple unrelated terminology articles were breaking the build
so I had to add vertical spaces; this is why they are part of this CR.

Compute Nodes

OpenStack compute nodes are, in many ways, the foundation of your environment; they are the servers on which your users will create their Virtual Machines (VMs) and host their applications. Compute nodes need to talk to controller nodes and reach out to essential services such as RabbitMQ and MySQL. They use the same approach that provides redundancy to the end-users of Horizon and REST APIs, reaching out to controller nodes using the VIP and going through HAProxy.
