[Feature request] multi-threaded and multi-connection download

[cjh0613]

What's the problem this feature will solve?

Download speed too slow

too slow!!

Describe the solution you'd like

1. Support for downloading using multi-threaded download tools, such as aria2c, when pip install --aria2c-download <path-to-aria2c> and support some other flags like how many threads
2. Multi-Connection Download. (can download a file from multiple sources)

Alternative Solutions

Perhaps you can implement these two functions in python

Additional context

Thanks!!!

Hello! Thanks for filing this. We already have this, in the form of --use-feature=fast-deps which does perform such parallel downloads. Beyond that #8187 covers this and a lot more, so I'm going to close this as a duplicate! :)
