build essential packages are needed for subprocess32

[Ibad Khan]

While producing wheels image from upper-constraints, docker build commands fails with error

Could not find a version that satisfies the requirement subprocess32 (from cmd2===0.8.0->-c /tmp/wheels/upper-constraints.txt (line 395)) (from versions: )
No matching distribution found for subprocess32 (from cmd2===0.8.0->-c /tmp/wheels/upper-constraints.txt (line:395))

Upon attempting to install subprocess32 on an out of box Ubuntu, found that following packages are necessary

1. gcc
2. make
3. build-essential
4. python-dev

loci install pip packages with few flags, so installing these packages isn't going to fix the issue.
