Builds a docker image using Dockerfile.builder and to be used as the base
image used in the setup_ubuntu_dev_env.sh.  The host ssh keys can also be
mounted in the docker to facilitate git usage. The docker image will take some
time to build the first time this script is run.

Usage: $0 [options] -- NP4_TAR
    [--pull]                        pull the latest debian base image
    [--mount-ssh]                   mount the HOME/.ssh directory into the docker image
    [--bazel-cache <path>]          mount the provided directory into the docker image and use it as the Bazel cache;
                                    default is HOME/.cache
    [--git-name <name>]             use the provided name for git commits
    [--git-email <email>]           use the provided email for git commits
    [--git-editor <editor command>] use the provided editor for git
    [-- [Docker options]]           additional Docker options for running the container

Example:
    $0 -- ~/np4_intel_4_7_1-1.tgz
