Currently ZUUL_USER_SSH_PUBLIC_KEY must be a key file, but
there is no change to create the key file, so it not convenient
for building a image with diskimage-builder, this patch makes
it possible to set ssh public key through ZUUL_USER_SSH_PUBLIC_KEY
in envirement(e.g. diskimage configuration in nodepool.yaml ).

The devuser element is designed to add a single development user and
manage their keys. Any local use of devuser by a developer thus
silently conflicts with zuul-worker.
Additionally, this is currently tacitly taking the public-key from
~/.ssh/id_rsa.pub -- i.e. the public key of the currently building
user. Mixing permissions from the builder into the final-image makes
sense for a development-user case, but not for deploying worker
accounts.
This simply creates the worker account by hand, which is easy enough.
To maintain the status-quo we still source ~/.ssh/id_rsa.pub by
default, but provide a documented flag to override this.
