Dockerfile.lerna

# The aim for the base image here is to only keep package*.json files while having the
# same directory structure to be able to have lerna dependencies installed once and cached
# as long as the package*.json files have not changed. In the future, we can further optimize
# it by creating slim package files that only contain *dependencies and name keys.
