Updates the documentation of the CLI to match the options supported
Also adds some type checking to the CLI for input UUID, and sets some
default values for OS auth variables that can be reasonably defaulted
Sets up the options on input to the output format to use 'cli' as the
default instead of 'format', providing for a path to make more cli
friendly outputs for actions (instead of raw json/yaml as appropriate).
Fixes some markdown in html problems.
