Swagger refactor/cleanup

* Remove duplicate or unused types and constants
* Move all documetation-only models and responses into swagger package
* Remove all unecessary names, go-swagger will determine names from
  struct declarations
* Use Libpod suffix to differentiate between compat and libpod models
  and responses. Taken from swagger:operation declarations.
* Models and responses that start with lowercase are for swagger use
  only while uppercase are used "as is" in the code and swagger comments
* Used gofumpt on new code
