Refactorator would like to apply these changes to your code!  Please shepherd this to production as soon as possible, going through the normal deployment process monitoring this PR as you would any other change.

**You are responsible for merging this PR in, Refactorator will not automatically commit any code.**

To reproduce these changes locally, run:

control run refactorator.run fix --images superset -f removeopensslpin
```
# removeopensslpin
Our version of Python 3.6.1 required openssl and libssl-dev to be pinned to match the version in our private aptly repo.

This has since been fixed with the version of 3.6.2 that has been released to aptly.  We have to remove the old pins because we need to remove our private openssl version from aptly as it has known problems.

This is safe to deploy since any new hosts in production will come up with Python 3.6.2 instead of 3.6.1.
