Code Issues Proposed changes

Require at least cryptography>=2.7

Browse Source 
Version 2.6 of the cryptography library [1] added support for ed25519
ssh keys. This works with OpenSSL >= 1.1.1b.

In nova, we can enable people to use ed25519 ssh keys by using the
necessary cryptography library version. Users must make sure they have
a new enough OpenSSL version, else they won't be able to generate
ed25519 ssh keys using ssh-keygen in the first place. I did a local
test using Ubuntu 18.04 and things "just worked" when I generated a
ed25519 ssh key and imported it into nova. I left a comment on the
launchpad bug accordingly.

This updates our minimum version to the latest available version 2.7.

Closes-Bug: #1555521
