* add a few example requests for endpoints that do not use bodies

* Remove x-codeSamples from overlay

* restructure existing examples w/o bodies as request examples

* skip examples w/o bodies when generating openapi examples

* add a lot of missing examples

* remove duplicate test

* more examples missed in previous commit
