Add command to install pypi packages by pip

AddonManager code uses legacy patterns, so I tried to follow the style as much as possible to keep the changes minimal.

I used the icon of PyPi for the command. I am not sure if we can use it.

@chennes
probably _cleanup_old_package_versions does nothing because the whole vendor_path is replaced with a new one, but i left it untouched for know, you know better this code and all the portability gotchas.

I think we probably shouldn't use the PyPI logo: we're basically a pip frontend, and not actually associated with PyPI, PyPA, or PSF. If it was a link directly to pypi.org it would probably be OK, but as the logo for a command that peripherally uses PyPI it's probably not (or at least, not clearly-enough OK for us to use it).

Ok, removed.

This works fine as long as I apply #397 (oops). I notice there's no pip output to the console, though, which I thought was strange. Is that supposed to be happening?

[mnesarco]

I did't remove any console output, and tried to keep the changes minimal. Let me check if I broke something

[mnesarco]

What i can see is that pip output goes to log, not console? It was not changed.

Edit: No, this is not the Issue.

Wait, in my local env I get full pip output in the console:
