Fixes #1709

This adds a new cacheKeyWillBeUsed lifecycle callback, following the interface described at #1709 (comment). This allows developers to override the default cache key for reads or writes (or both), for requests that pass through our cacheWrapper interface.

Once it's released, we'll need to update https://developers.google.com/web/tools/workbox/guides/using-plugins with info on usage.

Repeat code? Looks like these two tests are the same as the ones above.

They're in different describe() blocks—one for .put() and the other for .match(). The actual test cases are different, too.

In particular, the tests confirm that the correct mode value ('read' or 'write') is passed in to the plugin, and that the underlying cache.match() or cache.put() operation is actually called with the plugin's return value.

Ahh, I see. I couldn't easily see the outer blocks from the diff.
