Added helper script to run multiple tox environments

[antonpirker]

Description

This adds a simple helper script ./scripts/runtox.sh that allows people to run multiple tox environments with one call.

So ./scripts/runtox.sh py312 will run all tox environments having the string "py312" in their name.

This is helpful if you want to run all tox environments in one Python version, or run one environment in all Python versions. (like this: ./scripts/runtox.sh opentelemetry-api)

Constributed the same thing in opentelementry-python-contrib:
open-telemetry/opentelemetry-python-contrib#2763

I like the idea of automating things, but for this case tox -f can't solve the problem? Maybe we can just improve our docs to make it explicit

$ tox -f py312

And

$ tox -f opentelemetry-api

I know we have some issues with tox that makes some packages to leak during runs, like the issue that happened here with fastapi-slim: open-telemetry/opentelemetry-python-contrib#2756, but I think it's a problem with the way tox works.

wait what? 😅

I think its not a problem in our documentation but in toxs. I stumbled upon this command line arg in their docs but it says this:

-f FACTOR - factors to evaluate (passing multiple factors means 'AND', passing this option multiple times means 'OR') (default: [])

Which did not mean anything to me.

Ok then, ignore my PR (will go and remove runtox.sh from Sentry now 😄 )

tox can do what this script does, so it is useless! Closing this!
