Cryptography versioning style has changed

[zexoor]

Describe the bug

Currently the requirements.txt states that the highest compatible version for cryptography is 4.0.
Looking at the PyPi repo release history you can see that after version 3.4.8 they have changed their versioning system such that the subsequent version is 35.0.0

This may not actually be a bug and 3.4.8 may be the last compatible version released, but it would be good to have clarification on this

Reproduction steps

1.On a system running container-service-extension
2.Attempt to update cryptography to a newer version 
3.run 'cse version'

Expected behavior

Returns the currently installed version of CSE
