Update quickstart.md

added "--upgrade" option allzpark install in venv (under "Trouble Shooting/Permisison denied")

Thanks for this, except it's not clear what --upgrade adds? It means that if allzpark was already installed, pip would normally ignore the command. But with --upgrade it would compare the version installed with the latest version, and upgrade if a newer one exists.

Since this is happening in a virtual environment, where allzpark is guaranteed to not exist, upgrade does not seem necessary. Am I getting that right?

I honestly don't know. All I can say is that it didn't work for me without the --upgrade option

Ok, I'm going to hold onto this PR until we can confirm the instructions are correct and have been tested at least once more.
