Need a proper way to validate YAML format which could be part of linters as well

[rakeshgm]

including yaml validation could solve issues like this: red-hat-storage@1faf429 .

We use yamllint in the linters, but ignore the config directory as it has a lot of autogenerated files that do not pass the yaml linter settings. The potential fix would be to include the config directory and adjust the linter such that these autogenerated files do not show linter errors.
