LUDOC-270 protocol: Update the outline and add support files

This patch modifies the outline to the document:
- Orgainizing the presentation a little better
- Removing empty sections until they are ready to be included
- Breaking main topics out into separate files
The organization is bottom-up in that it starts with a Dtat Types
Section, builds on that by showing how messages are structured, then
addresses how the Lustre operations use those messages, and finally
how file system activitiy uses Lustre oparations to carry out its
activities.
