Add install zookeeper role; use for nodepool-builder testing

This adds a simple role to install Zookeeper.

Add an option to nodepool-base to use this role to install Zookeeper.

Use this in the nodepool-builder gate testing where we are just
validating that the nodepool-builder container starts and is ready to
accept connections.  It needs a zookeeper to talk to, even though it
is not going to do anything.

.. zuul:rolevar:: nodepool_base_install_zookeeper
Install zookeeper to the node. This is not expected to be used in
production, where the nodes would connect to an externally
configured zookeeper instance. It can be useful for basic loopback
tests in the gate, however.
