Subject: [PATCH] images: Install coreutils package

The current kubernetes-entrypoint image [0] is missing the echo binary,
resulting in errors:

  Entrypoint ERROR: 2019/10/14 18:34:58 kubernetes-entrypoint.go:38:
  Cannot execute command: exec: "echo": executable file not found

This change installs the coreutils package to the kubernetes-entrypoint
image in order to make the echo binary available.
