Anyway to suppress warnings on Mac when running podman machine start

[pellcorp]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind feature

Description
An environment variable or config setting to hide the messages you get when using podman machine start on MacOS. The messages I mean are:

This machine is currently configured rootless ...

and:

The system helper is not installed ....

and:

You can still connect docker API clients...

Steps to reproduce the issue:

1. on MacOS run podman machine start.

Describe the results you received:

$ podman machine start
Starting machine "podman-machine-default"
Waiting for VM ...
Mounting volume... /Users/pellcorp:/Users/pellcorp

This machine is currently configured in rootless mode. If your containers
require root permissions (e.g. ports < 1024), or if you run into compatibility
issues with non-podman clients, you can switch using the following command: 

	podman machine set --rootful

API forwarding listening on: /Users/pellcorp/.local/share/containers/podman/machine/podman-machine-default/podman.sock

The system helper service is not installed; the default Docker API socket
address can't be used by podman. If you would like to install it run the
following commands:

	sudo /opt/homebrew/Cellar/podman/4.2.0/bin/podman-mac-helper install
	podman machine stop; podman machine start

You can still connect Docker API clients by setting DOCKER_HOST using the
following command in your terminal session:

	export DOCKER_HOST='unix:///Users/pellcorp/.local/share/containers/podman/machine/podman-machine-default/podman.sock'

Machine "podman-machine-default" started successfully

Describe the results you expected:

$ podman machine start
Starting machine "podman-machine-default"
Waiting for VM ...
Mounting volume... /Users/pellcorp:/Users/pellcorp
Machine "podman-machine-default" started successfully

Additional information you deem important (e.g. issue happens only occasionally):

whats the problem with it?

I assume that @pellcorp is looking for a --quiet option that would suppress the output. @pellcorp can you elaborate?
