Tox in verbose mode?

首先检查 action 和容器如何处理 TOX_PARAMS，然后将默认安装输出与 issue 中描述的 -vvvvv 行为进行比较。明确详细程度应属于 action 还是容器配置，并考虑报告中提到的用户覆盖设置。当安装过程提供所请求的诊断详细信息，同时不阻止用户设置覆盖该详细程度时，即视为完成。

It might be useful to have tox in more verbose mode than the default. I'm gonna explain what happened to me recently. I've prepared a CI job with fedora-python-tox. The test dependencies contain one which has to be compiled from sources and therefore needs some non-Python deps to be installed in the container in advance. If the system package is missing, pip fails to install (compile) the package, and instead of exiting with an error, it keeps trying with older and older versions of the same package all failing for the same reason. This ended up after hours because of timeout. To uncover the problem, I had to manually add

      env:
        TOX_PARAMS: -vvvvv

to the config to see what's happening during the installation process.

I know that the verbose mode might produce a lot of logs but having a log of the installation process sounds reasonable to me. What do you think? Should this be done on the action or container image level? I believe that both can be overwritten by user settings.
