pip --only-binary=:all: option is not an exact replacement of --use-wheels

[humitos]

On today's deploy we found that mock==1.0.1 is not installable with --only-binary=:all: option but it was installable with the --use-wheels.

I tested this locally before deploying but it did work in my instance, so I was probably using a different version of pip or something like that. We are using pip 9.0.1 in production.

We need to keep discussing this.

For now, we revert the PR #4206 that introduces this change.
Revert PR at #4261

It seems like --use-wheels was like prefer wheels instead of force them. I think that maybe new pip versions do that by default and no option is needed.

Ok, I couldn't find the changelog for this, but I found this in the docs

Pip prefers Wheels where they are available. To disable this, use the --no-binary flag for pip install.

If no satisfactory wheels are found, pip will default to finding source archives.

So, we only need is to remove that option :).
