Fix all the resting errors to have a valid swagger file.
They are still some warnings but nothing blocking.
Doing so I found that some request still misses son parameters for some POST/PUT/PATCH request. This means the a client generated from the swagger file will not work completely.
Fix #4088 by activating validation in drone
Should fix #4010.
* Partial fix for #4010
Swagger needs a description field in each swagger:operation response. Adding
minimal text for now on the way to getting swagger validate to pass. Many
standard swagger client libraries will not work with gitea until validate
passes, so prioritizing that over better descriptions for now.
