[action] [PR:15208] Ansible error formatting

[mssonicbld]

Description of PR

Summary:
Revises ansible error output to be custom formatted such that it prints in the following order:

1. Random fields that don't involve readable text printing, such as the command used or how long the test ran.
2. stdout_lines formatted with proper newlines.
3. stderr_lines also formatted.

The output is sorted with the most interesting failure information at the bottom, namely the stderr.

Approach

What is the motivation for this PR?

How did you do it?

How did you verify/test it?

Inserted an artificial error on a Cisco-8000 series device, observed below output (trimmed out the tail of the cmd and invocation fields):

Any platform specific information?

Will affect all platforms.

Supported testbed topology if it's a new test case?

Will affect all topologies.
