    @mmiklavc. One potential solution is to use changeAnsibleControlPath() to 
set the  
["ANSIBLE_SSH_CONTROL_PATH"](https://docs.ansible.com/ansible/2.4/config.html#envvar-ANSIBLE_SSH_CONTROL_PATH)
 environment variable before running the playbook. 
    
    With this PR's existing code the only change that would need to be done is 
commenting out the #sed command between the if-fi and replacing it with the 
following:
    ```
    export ANSIBLE_SSH_CONTROL_PATH=$(echo $ansiblecontrolpath)
    ```
    
    With this approach the environment variable seems to override the 
control_path in ansible.cfg and the ansible.cfg does not get changed. 
    
    I tested the line change in MacOS (ansible v 2.2.2.0) by doing the following
    -Intentionally put a bad control_path in ansible.cfg and run run.sh without 
changeAnsibleControlPath (expecting an error).

    -Next I updated run.sh with the "export ANSIBLE_SSH_CONTROL_PATH" line 
change in changeAnsibleControlPath(). It was able to get it running past TASK

    I didn't test with the Linux operating systems yet.
