docs: updates and move traffic gens to separate doc

Move the traffic gen instructions to a separate user guide and add
information on usage of the Dummy traffic generator. Update docs
to fix PDF build failure and do general clean-up. Removed the numbering
from the LTD and added the numbered directive to automate numbering for
sections and headers. Add comment anchors that reflect the section
numbers.
