Update deployment prerequisites to remove pyopenssl errors
Over the weekend, pyOpenssl 20.0 was released.  This causes an incompatible library issue during deployment.
Prior to this change, deployment would generate the following error
```
ERROR: pyopenssl 20.0.0 has requirement cryptography>=3.2, but you'll have cryptography 2.9.2 which is incompatible.
