# builds and pushes Docker images
# expectations:
#   - directory structure is: {image}/{os}/{os-branch}, e.g. jenkins/windowsservercore/ltsc2016
#   - Dockerfile and context are in the {os-branch} directory
#   - this command is executed from the {os-branch} directory
# input:
#   - imageVersion - version of the image being built
#   - registryUser - registry username or organization
#   - localRegistry - registry push destination, in addition to Docker Hub
#   - buildArgs - comma separated values to pass as `build-arg` in Docker build
# output:
#   - image built and pushed with multiple tags using the format {user}/{image}:{version-{os}-{os-branch},
#   - e.g. 
#   -  sixeyed/jenkins:2.121.1-windowsservercore-ltsc2016
#   -  sixeyed/jenkins:windowsservercore-ltsc2016
#   -  sixeyed/jenkins
