Improvements to boolean flags

• backward incompatible changes to how boolean flags are handled
• Common/Vanilla case of debug:bool = False can be customized with (-d, --debug) to negate the default value.
• Required x:bool, or x:Optional[bool], x:Optional[bool] = None semantics remain the same with (--enable-x, --disable-x) format.
• Use Pydantic's Field instead of Config.CLI_EXTRA_OPTIONS to have one consistent model
• Improve help messages by adding better type description and explicitly display if a field is required
