Fix stable-1 for new cryptography 37.0.0 release (#446)

* Fix empty check for openssl_pkcs12 tests.

* Prevent crash if PyOpenSSL cannot be imported because of an AttributeError.

* Add changelog fragment.

* Fix constraints file.

* Use Python 2.7 instead of 3.5 for 2.9 cloud tests (pip module is broken).

* Prevent upgrading cryptography on ansible-core 2.12's default container with Python 3.9.
