This avoids the conflict with the zuul user (1000) on the test
nodes. The executor will continue to use the default username
of 'zuul' as the ansible_user in the inventory.
This change also touches the zk and nodepool deployment to use
variables for the usernames and uids to make changes like this
easier. No changes are intended there.

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.
