* 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 ```release-note ``` Signed-off-by: Jhon Honce <jhonce@redhat.com>
