`pip install git+...` from a branch/tag could be faster

What's the problem this feature will solve?

pip install git+...@foo-branch clones the whole repository and then checks out foo-branch. This process takes some time if the repository has a long history or many branches.

Describe the solution you'd like

I'd like to leverage git clone parameters to make the whole thing faster when a specific branch is requested. In particular, I'd use `the following:

• --branch foo-branch
• --depth 1

Alternative Solutions

The current solution works fine, but is slow in some specific situations.
