Add ability to build images in play kube
When playing a kube YAML file, it can be desirable to be able to build an image on the fly. This is good for development of an image and YAML files and somewhat mocks what compose does. Signed-off-by: Brent Baude <bbaude@redhat.com>

+Play kube is capable of building images on the fly given the correct directory layout and Containerfiles. This
+option is not available for remote clients yet. Consider the following excerpt from a YAML file:
+```
+apiVersion: v1
+kind: Pod
+metadata:
+...
+spec:
+ containers:
+ - command:
+ - top
+ - name: container
+ value: podman
+ image: foobar
+...
+```
+
+If there is a directory named `foobar` in the current working directory with a file named `Containerfile` or `Dockerfile`,
+Podman play kube will build that image and name it `foobar`. An example directory structure for this example would look
+like:
+```
+|- mykubefiles
+ |- myplayfile.yaml
+ |- foobar
+ |- Containerfile
+```
+
+The build will consider `foobar` to be the context directory for the build. If there is an image in local storage
+called `foobar`, the image will not be built unless the `--build` flag is used.
