Refactor pre-Doxy siphon scripts; VPP-396
- Modularize the code to make the Siphon process easier to maintain. - Move much of the output rendering into Jinja2 templates. - Add syscfg siphon type for startup config documentation. - Add sample syscfg documentation. - Add clicfg and syscfg preamble docs, adapted from their wiki pages. - Fix sorting of CLI items across multiple directories. Change-Id: Ib8288fe005adfea68ceed75a38ff8eba25d3cc79 Signed-off-by: Chris Luke <chrisy@flirble.org>
