Make navigator image pulling silent

[ssbarnea]

Because podman in particular is overly verbose even when image is already present, we switch to a default quiet mode.

We need to discuss about this but as someone that wants to use navigator from the cli to run multiple commands, I find the current default console output extremely verbose.

To describe it as user story: as someone that uses ansible-navigator in stdout mode, I expect to see only the output of executed command on screen on subsequent runs. There is no need to be told about container pulling each time I run, same output again and again.

I would not mind seeing something when a container IS PULLED (change occurred), but not when it was already updated.

❯ ansible-navigator --mode stdout run tests/fixtures/integration/actions/stdout/site.yml
> ansible-navigator --mode stdout run

<< ANSIBLE OUTPUT (the useful output >>

@tima Please take a look at this, maybe even try to run the commands yourself to get an impression so we can decide if we are to make a change and if we how we should do it.

In fact is more about it, the entire data seen on screen is on stdout but the reality is that the text that I find annoying is effectively "logging" information, not the output of the executed command.

I can quote from one of our favorite resources https://clig.dev/#output

Send output to stdout. The primary output for your command should go to stdout. Anything that is machine readable should also go to stdout—this is where piping sends things by default.

Send messaging to stderr. Log messages, errors, and so on should all be sent to stderr. This means that when commands are piped together, these messages are displayed to the user and not fed into the next command.

To translate these for current case, I see the lines I want to remove as "messaging", and the ansible-playbook output as the "output" of the command.

Because the default is to pull if tag ==latest (which is right), there may be a delay in bringing up the TUI. As long as the user is provided an explanation and the additional information is available via a cli param, I'm fine with some changes.
