title: How do I toggle verbose mode for all commands inside tox.ini in a simpler way?
body: <p>Let us say I have a lot of commands inside my tox.ini</p>
  <pre><code>commands =
          poetry install -v
          poetry run pytest --typeguard-packages=news --xdoctest --cov -vv
          poetry run flake8 --verbose
          poetry run black src tests --verbose
          poetry run isort . --verbose
          poetry run bandit src --recursive --verbose
          poetry run mypy src --verbose
          poetry run darglint src --verbosity=2
          poetry run darglint tests --verbosity=2
  </code></pre>
  <p>Instead of repeating verbose everywhere, is there a way I can make all of them run with/without verbose in a simpler way?</p>
  <p>For example, if I ran</p>
  <pre><code>poetry run tox
  </code></pre>
  <p>it runs everything without verbose, if I remove the --verbose flag from everywhere
  but how do I make tox run all commands with verbose without hardcoding the verbose flag?</p>
