 Update to v47.0.0 
Full changelog: https://cryptography.io/en/latest/changelog/#v47-0-0

This release includes a number of backwards-incompatible changes:

 - Support for binary elliptic curves (SECT* classes) has been removed.
   These curves are rarely used and have additional security
   considerations that make them undesirable.

 - Loading keys with unsupported algorithms or keys with unsupported
   explicit curve encodings now raises UnsupportedAlgorithm instead of
   ValueError. This change affects load_pem_private_key(),
   load_der_private_key(), load_pem_public_key(), load_der_public_key(),
   and public_key() when called on certificates with unsupported public
   key algorithms.

 - When parsing elliptic curve private keys, we now reject keys that
   incorrectly encode a private key of the wrong length because such
   keys are impossible to process in a constant-time manner. We do not
   believe keys with this problem are in wide use, however we may revert
   this change based on the feedback we receive.

RHEL/CentOS builds

RHEL and CentOS use a different approach for Rust crates packaging than Fedora. On Fedora Rust dependencies are packaged as RPMs, e.g. rust-pyo3+default-devel RPM. These packages don't exist on RHEL and CentOS. Instead python-cryptography uses a tar ball with vendored crates. The tar ball is created by a script:

./vendor_rust.py
rhpkg upload cryptography-3.4-vendor.tar.bz2
