cfs-operator container can't build outside of HPE/Cray network

[alexlovelltroy]

There are two things that block building the cfs-operator container outside the Cray/HPE Network.

1. Several items are hard coded in the dockerfile and refer to internal build repositories. Parameterizing the Dockerfile with ARGS would solve this. I have a PR ready to go for that work.
2. cfs-operator relies on a liveness python library that isn't available yet through pypi. Parameterizing the build won't help unless liveness is available externally as well.
