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

+// Package server supports a RESTful API for the Libpod library
+//
+// This documentation describes the Podman v2.x+ RESTful API. It consists of a Docker-compatible
+// API and a Libpod API providing support for Podman’s unique features such as pods.
+//
+// To start the service and keep it running for 5,000 seconds (-t 0 runs forever):
+//
+//    podman system service -t 5000 &
+//
+// You can then use cURL on the socket using requests documented below.
+//
+// NOTE: if you install the package podman-docker, it will create a symbolic
+// link for /run/docker.sock to /run/podman/podman.sock
+//
+// NOTE: Some fields in the API response JSON are encoded as omitempty, which means that
+// if said field has a zero value, they will not be encoded in the API response. This
+// is a feature to help reduce the size of the JSON responses returned via the API.
+//
+// NOTE: Due to the limitations of [go-swagger](https://github.com/go-swagger/go-swagger),
+// some field values that have a complex type show up as null in the docs as well as in the
+// API responses. This is because the zero value for the field type is null. The field
+// description in the docs will state what type the field is expected to be for such cases.
+//
+// See podman-service(1) for more information.
+//
+//  Quick Examples:
+//
+//   'podman info'
+//
+//      curl --unix-socket /run/podman/podman.sock http://d/v4.0.0/libpod/info
+//
+//   'podman pull quay.io/containers/podman'
+//
+//      curl -XPOST --unix-socket /run/podman/podman.sock -v 'http://d/v4.0.0/images/create?fromImage=quay.io%2Fcontainers%2Fpodman'
+//
+//   'podman list images'
+//
+//      curl --unix-socket /run/podman/podman.sock -v 'http://d/v4.0.0/libpod/images/json' | jq
