improvement: don't check for commented options

1. the user configuration and options should be handled in the recipe/module. leaving these options in is nice, but not very maintainable since it may prevent us from using upstream modules/cookbooks for ssh management, which may not all have the option to add comments. since it's unnecessary, remove it
2. none of these commented options requires being set by compliance guidelines and sanity, so imho they are all fine to be removed
