Add default mpi-operator image

[vexingly]

fix: remove failing databricks-python image

This is not being used, it can be added again if needed. Failing build due to CVE in latest base image.

feat: add new mpi-operator based image

Added an mpi-operator based image instead of an openm++ based image.

• Base mpi-operator dockerfile from https://github.com/kubeflow/mpi-operator/blob/master/build/base/Dockerfile
• Added open-mpi https://github.com/kubeflow/mpi-operator/blob/master/build/base/openmpi.Dockerfile
• Added configuration for OpenM++ from https://github.com/openmpp/docker/blob/master/ompp-run-debian/Dockerfile
• Added kubectl cli for interacting with kubeapi server from containers
