Can we close #3720 in favor of this?

[jessemapel]

Looks reasonable. Once Jenkins is sorted, testing can be evaluated.

[kaitlyndlee]

Looks good to me after Jesse's comment is responded to.

Is there a way to parameterize the docker files? They look to be nearly identical

[Kelvinrr]

@jessemapel We can close #3720 in favor of this one. Once tests finish on Jenkins I think this is good to merge. Some module tests failed that I need to check out. If they look fine local I'll merge it. Most app failures are NFS failures.

Failing fedora unit test passed locally, so I'll assume it was a fluke and merge this.
