Unify setup of common stuff in elements

Registered by Matthew Farrellee

As the number of Hadoop distro dib image elements increase, we're getting duplication of the java installation code, ssh setup/config and other stuff.

Such code blocks should be refactored into its own elements, ideally into the elements that will be included in diskimage-builder itself.

List of currently copy-pasted elements that should be unified:

* java: https://github.com/openstack/savanna-image-elements/blob/master/elements/hadoop/install.d/20-setup-java

* ssh: https://github.com/openstack/savanna-image-elements/blob/master/elements/hadoop/post-install.d/30-setup-ssh
