Make git progress optional for use in CI contexts

• I've read and understood the CONTRIBUTING guidelines and have done my best effort to follow.

Report

What did you do?

pod update

or

pod install --repo-update

What did you expect to happen?

I wanted an option to disable the progress reporting from the underlying git command when running on our Continuous Integration server.

What happened instead?

The git progress was reported as hundreds of spammy console lines in our build log:

Why not use --silent

We don't want to completely disable all output, since it's still helpful to see the status updates of Cocoapods itself. We just don't want the interactive progress reporting in our CI pipeline.

Proposal

Add a --no-progress flag.
