Fix: Install python 3.10.x on CentOS 7

Python 3.10.x is a pre-requiste for the ansible version 9.2.0
used fro the packer jobs. However the version of python 3.10.x
requires openssl11 libs and headers to be installed so that pyenv
install builds the required runtime dependencies.

ERROR: "ModuleNotFoundErrorr No module named '_ssl'"
"The Python ssl extension was not compiled. Missing the OpenSSL lib?"
