Print total results banner at the end of execution

[alexluix]

As a user, I would like to see the final result of my execution indicating whether the execution was successful or not. Additionally, it would be useful to see total execution time for all executed commands.

In case of failed execution – I would like to see the phase that failed and exit code just in case.

Acceptance Criteria

1. introduce status banner at the end of the last executed phase – this banner appears always at the end – in case of successful execution or at the end of the failed phase
2. Example of a successful banner – width of the lines must be 72 characters:

------------------------------------------------------------------------
SUCCESS - Total time: 8s
------------------------------------------------------------------------

3. Example of a failed banner:

Execution failed: phase 'a' - exit code: 127
------------------------------------------------------------------------
FAILURE - Total time:  1m 53s
------------------------------------------------------------------------

Notice that the line with Execution failed is a replacement of the current failure message. We are changing the format of the message to be more minimalistic.

4. Success and Failure keywords should be coloured as the following:

   • SUCCESS – CYAN
   • FAILURE – RED

5. Total time

   • In min & sec
   • example:
     • 9s
     • 28s
     • 1m 59s
     • 7m

See the attached screenshot as an example.
