All lookups ported to config system (#74108)

* all lookups to support config system

 - added get_options to get full dict with all opts
 - fixed tests to match new error messages
 - kept inline string k=v parsing methods for backwards compat
 - placeholder depredation for inline string k=v parsing
 - updated tests and examples to also show new way
 - refactored and added comments to most custom k=v parsing
 - added missing docs for template_vars to template
 - normalized error messages and exception types
 - fixed constants default
 - better details value errors
