Make sure the user knowns that a git command is run.
From the issue #4588:
> It is confusing at times, when executing some CLI command, expecting change,
then checking git status but no changes are observed.
We now log:
- git add (debug)
- git commit (info)
The git commit information is formatted the following way:
```
Committed machines/backup-target to git
```
Alternatives:
Currently this shows to the user what happened.
But we might want to show the user what is being run.
We could print the information before invoking the `git commit` itself.
Informing the user of a potential password input window.
Closes#4588
