play: kube: use in-memory kubefile and remove tempfile

The PlayKube and PlayKubeDown commands accepted a "path" argument to a YAML file
to play. This requires the caller to write the YAML to a file path. The downside
of this is apparent in the HTTP handlers which have to use a temporary file on
disk to store the YAML file.

The file is opened & used as the body of the HTTP request. It's possible to
instead pass a io.Reader and use a fully in-memory request body.

Add backwards-compatible changes to bindings to allow passing either a filepath
or a io.Reader body.

Refactor the podman bindings to use a io.Reader instead of a filepath.

Simplify the HTTP handlers for PlayKube by removing the now unneeded tempfile.

[NO NEW TESTS NEEDED]
