Proposal: Integrate structured logging

[tboerger]

So far the logs are pretty minimalistic, I think it is a good idea to integrate a structured logger which also gets metadata attached. By default it's human-readable formatted and optionally can get switched to json output.

Options could be the recent golang slog package or github.com/rs/zerolog.

This would be an excellent improvement, the company I work for has recently been evaluating Semaphore UI and would be interested in Premium+/Enterprise support but coming from AWX/AAP the logging is lacking. Particularly the task metadata is important for us to have (who ran the task, survey options, cli options, playbook name, template name, repo, etc - particularly survey/vars). It'd also be cleaner to be able to get more verbosity per task without having to set the whole template output to debug (-vvvv), or at least be able to set the verbosity lower (-vvv).

Overall I think it meets our needs for the majority of tasks. I like the simplicity of it, single rpm upgrades are awesome and caching Galaxy collections locally has been a bonus. Keep up the good work!
