Fix SSH transport for Ansible server

with previous configuration of ansible server docker, as there was no
ssh binary, ansible switched to paramiko and it was causing "cannot
import name aead".

Added "ssh" as binary and tried to make paramiko work as some modules
requires it (such as PAN-OS). but it still fails with the same error...

Also given "ansible-server" to ansible user as it can create
PlaybooksTemp (wasn't allowed before).
