Is not working as expected - does not add config files into alertmanager/prometheus.

This modifies Dockerfile.build.* to run unit tests before build.

This adds support for private docker registries, by adding
an optional `registryAuth` field in the CreateFunctionRequest.
Auth must be passed as base64-encoded basic auth, similar to
how done in Docker file store credentials (~/.docker/config.json).
Credentials are then passed to swarm at service creation.

* Add try in pwd button.
