Allow run 'ping' as non-root user

[definitio]

There is a problem with alpine images that prevents executing 'ping' as non root user.

Thanks for opening this PR. I suggest starting the image with -e "PACKAGES=iputils", which installs the non-busybox version of ping (with the correct permissions). This is hinted at in the README, but maybe you have an idea how to make the documentation clearer?

I read the README. Installing packages on start is bad solution because it prevents Home Assistant to start without Internet connection:

Thanks for bringing this up. It still feels like we should have a more generic way to solve the problem. 🤔
