removing some unusued files. Paramiko alt was an experiment to attempt pipeline… 

removing some unusued files.  Paramiko alt was an experiment to attempt pipeline for paramiko, ssh_old is the non-pipelining-supported earlier
version of the OpenSSH transport, which is configurable now and unified.

# The paramiko transport is provided because many distributions, in particular EL6 and before
# do not support ControlPersist in their SSH implementations. This is needed on the Ansible
# control machine to be reasonably efficient with connections. Thus paramiko is faster
# for most users on these platforms. Users with ControlPersist capability can consider
# using -c ssh or configuring the transport in ansible.cfg.
