Setting an ansible.cfg file

Setting a default ansible config file in the working folder in order
to enable pipelining and extend the SSH timeout as some processes
are long running.

Ansible will automatically load this file if the user executes
ansible-playbook from the folder where the file is sitting, if
system-wide or user-specific configuration files are not found.
