IMPALA-4427: leopard: make DOCKER_IMAGE_NAME required
This patch now requires users of the Leopard framework to supply a
DOCKER_IMAGE_NAME. The cloudera/impala image isn't being maintained, and
until Apache Impala (incubating) decides to publish its own image, no
default image name is possible. It is still possible to run the Leopard
framework against a homegrown Docker image that has Apache Impala
(incubating) and PostgreSQL installed: simply build such an image and
export the DOCKER_IMAGE_NAME environment variable before running the
While here, fix some flake8 non-indent problems.
Testing: short Leopard controller / query generator run.
