Return a directory to store cached wheels in for link.
Because there are M wheels for any one sdist, we provide a directory
to cache them in, and then consult that directory when looking up
cache hits.
We only insert things into the cache if they have plausible version
numbers, so that we don't contaminate the cache with things that were not
unique. E.g. ./package might have dozens of installs done for it and build
a version of 0.0...and if we built and cached a wheel, we'd end up using
the same wheel even if the source has been edited.
:param cache_dir: The cache_dir being used by pip.
:param link: The link of the sdist for which this will cache wheels.

Pip should refuse to install a Wheel-Version that's a major series
ahead of what it's compatible with (e.g 2.0 > 1.1); and warn when
installing a version only minor version ahead (e.g 1.2 > 1.1).
