Migrate from Crypto to M2Crypto

[Ch3LL]

For oxygen we will be migrating to M2Crypto. This issue will track the work needed to complete this migration.

Without knowing the context, M2Crypto is Py2.7 only, right? I thought Salt even ditched it a while back for that reason?

1. M2Crypto developers are working on Py3 support and now it's possible to build it for Py3 from the python3 branch.
2. Crypto support wasn't dropped. Salt will fallback to Crypto if M2Crypto isn't installed.

Well that's extremely recent news then ;) tnx 4 the update

This seems to be a bad choice, given open stack is now gaining ground in Linux and Non-Linux, and uses a different library see #30287

We are making the crypto backend modular so that we will also be able to build in support for the cryptography library as well.
