update cryptography to allow either 3.4.8 or 36.0.1 and earlier

[pabs3]

There is a cryptography 3.4.8 that updates the OpenSSL version used, please update the dependencies to allow it.

Also, 36.0.1 is out that rewrites parts of the codebase in Rust, so it should be much safer, please look at allowing that version:

This is especially important since cryptography 35.0.0 added support for OpenSSL 3:

We have picked this task up and are evaluating on removing the upper-bound for cryptography in OCI Python SDK. We will update you soon on its progress.

@pabs3 we increased the upper bound for cryptography. Will evaluate a bit more on removing in future release
