Fix ansible tasks profiling

This MR fixes the deprecated profiling settings in the ansible.cfg. The deprecated option that enables task profiling callback_enabled was
replaced by the option callbacks_enabled.

Note:

The profile_tasks is an ansible callback plugin for timing individual tasks and overall execution time

• Format: <task start timestamp> (<length of previous task> <current elapsed playbook execution time>)
• It also lists the top time-consuming tasks in the summary
• See example here
