Parse a playbook execution log

[xanderjjj]

It would be nice as a debugging tool if we could parse a playbook execution log and for a given host in the inventory, and colourise the tasks in the graph depending on their execution result (successful, skipped, changed, failed).
This could also be used to hide tasks that don't get run.
Suggested args --execution-log, --hostname and --hide-skipped

Yeah that's a nice idea. Will see how this can be done. This makes me think about (https://github.com/openstack/ara) that doesn't have the graph part and use ansible callbacks
