Building a self-contained package

The generic-k8s-webhook can now be packaged into a self-contained
package, so this package can be executed without the need of installing
any extra dependency. To do so, we're leveraging pyinstaller.

Now, when we'll build a new release, we'll push this self-contained
package as part of the release.
