Boost deployment time

[rsevilla87]

Description

In order to cut down deployment time of new clusters, several tasks, that take a few minutes, can be executed in parallel with the help of the async statement, and then we can poll them with async_status.

Deployment time of a 6 node cluster (3 masters + 3 workers) seen with the original code was: Thursday 06 October 2022 21:17:21 +0000 (0:00:00.402) 1:32:37.115 ******

With the patch was: Monday 10 October 2022 12:15:55 +0000 (0:00:00.397) 1:15:51.220 ********

That means a time saving of ~15minutes

Also updating ansible.cfg to enable pipelining and replace the deprecated callback_whitelist by callbacks_enabled to suppress deprecation warnings in the output.
