RFE: Replace paramiko with libssh

[sadsfae]

python3-paramiko is going to be removed in EL8 in lieu of libssh and in other places as well (like Ansible). Overall, libssh proves some very tangible performance benefits over paramiko along with no real dependencies as it uses the system C libraries.

We should look instead to package and utilize python3-ssh2-python which provides the Python wrapper integration into libssh

Leaving this on hold for the time being. Not able to execute more than 1 command in 1 session and not much support for this python library.
