Tone down sortpom output

[gnodet]

When using spotless to format a number of POMs, I end up with:

I'd like to introduce a flag to done down the log to debug instead of info.

Sounds reasonable. Maybe a flag “quiet” that removes all output from the plugin?

Hi! Just wanted to say that I have not forgotten this issue. I’m away at a family vacation at the moment, and so far programming has not been on the menu.

No problem, enjoy your vacation time !

Branch issue-338-Tone_down_sortpom_output created!

[Ekryd]

I created a branch for the quiet flag. (I refactored the code a bit)
@gnodet, can you submit a PR for the branch with an integration test? Similar functionality as maven-plugin/src/it/four-spaces-indent

[Ekryd]

Hi @gnodet !
I have just released version 3.3.0 of the plugin with the new quiet flag.
Please try it out and see if it works for you
