Man pages: refactor common options: authfile

Refactor the --authfile option.

My suggestion for review:
  1) run hack/markdown-preprocess-review and immediately Ctrl-Q to
     quit out of diffuse, which is completely unusable for this
     many files; then
  2) cd /tmp/markdown-preprocess-review.diffs/authfile
     - this is the directory created by the review script
  3) rm podman-image-sign* podman-log* podman-search.1.md.in
     - because they're essentially identical to podman-create
  4) rm podman-manifest-* podman-push.*
     - because they're 100% identical to podman-kube-play
  5) rm podman-kube-play*
     - because it's apart-from-whitespace identical to podman-build
       (use "wdiff" to confirm)
  6) rm podman-auto-update*
     - because that's the one I chose (hence == zzz-chosen.md)

(You should obviously run your own diff/cmp before rm, to confirm
my assertions about which files are identical).

After all that, you have a manageable number of files which
you can scan, read, diff against zzz-chosen.md, even run diffuse.

This option is IMHO the poster child for why we need this kind
of man page refactoring.

+## NAME
+podman\-manifest\-add - Add an image to a manifest list or image index
+
+## SYNOPSIS
+**podman manifest add** [*options*] *listnameorindexname* [*transport*]:*imagename*
+
+## DESCRIPTION
+
+Adds the specified image to the specified manifest list or image index.
+
+## RETURN VALUE
+The list image's ID.
+
+## OPTIONS
+
+#### **--all**
+
+If the image which should be added to the list or index is itself a list or
+index, add all of the contents to the local list.  By default, only one image
+from such a list or index will be added to the list or index.  Combining
+*--all* with any of the other options described below is NOT recommended.
+
+#### **--annotation**=*annotation=value*
+
+Set an annotation on the entry for the newly-added image.
+
+#### **--arch**
+
+Override the architecture which the list or index records as a requirement for
+the image.  If *imageName* refers to a manifest list or image index, the
+architecture information will be retrieved from it.  Otherwise, it will be
+retrieved from the image's configuration information.
+
+@@option authfile
+
+#### **--cert-dir**=*path*
+
+Use certificates at *path* (\*.crt, \*.cert, \*.key) to connect to the registry. (Default: /etc/containers/certs.d)
+Please refer to containers-certs.d(5) for details. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)
+
+#### **--creds**=*creds*
+
+The [username[:password]] to use to authenticate with the registry if required.
+If one or both values are not supplied, a command line prompt will appear and the
+value can be entered.  The password is entered without echo.
+
+#### **--features**
+
+Specify the features list which the list or index records as requirements for
+the image.  This option is rarely used.
+
+#### **--os**
+
+Override the OS which the list or index records as a requirement for the image.
+If *imagename* refers to a manifest list or image index, the OS information
+will be retrieved from it.  Otherwise, it will be retrieved from the image's
+configuration information.
+
+#### **--os-version**
+
+Specify the OS version which the list or index records as a requirement for the
+image.  This option is rarely used.
+
+#### **--tls-verify**
+
+Require HTTPS and verify certificates when talking to container registries (defaults to true).
+
+#### **--variant**
+
+Specify the variant which the list or index records for the image.  This option
+is typically used to distinguish between multiple entries which share the same
+architecture value, but which expect different versions of its instruction set.
+
+## Transport
+
+ Multiple transports are supported:
+
+  **docker://**_docker-reference_ _(default)_
+  An image in a registry implementing the "Docker Registry HTTP API V2". By default, uses the authorization state in `$XDG_RUNTIME_DIR/containers/auth.json`, which is set using `(podman login)`. If the authorization state is not found there, `$HOME/.docker/config.json` is checked, which is set using `(docker login)`.
+
+    $ podman manifest add mylist:v1.11 docker://quay.io/username/myimage
+
+  **containers-storage:**_oci-reference_
+  An image in _oci-reference_ format stored in the local container storage. _oci-reference_ must contain a tag.
+
+    $ podman manifest add mylist:v1.11 containers-storage:quay.io/username/myimage
+
+  **dir:**_path_
+  An existing local directory _path_ storing the manifest, layer tarballs, and signatures as individual files. This
+  is a non-standardized format, primarily useful for debugging or noninvasive container inspection.
+
+    $ podman manifest add dir:/tmp/myimage
+
+  **docker-archive:**_path_[**:**_docker-reference_]
+  An image is stored in the `docker save` formatted file.  _docker-reference_ is only used when creating such a
+  file, and it must not contain a digest.
+
+    $ podman manifest add docker-archive:/tmp/myimage
+
+  **docker-daemon:**_docker-reference_
+  An image in _docker-reference_ format stored in the docker daemon internal storage. The _docker-reference_ can also be an image ID (docker-daemon:algo:digest).
+
+    $ sudo podman manifest add docker-daemon:docker.io/library/myimage:33
+
+  **oci-archive:**_path_**:**_tag_
+  An image _tag_ in a directory compliant with "Open Container Image Layout Specification" at _path_.
+
+    $ podman manifest add oci-archive:/tmp/myimage
+
