Fixes #2146

This PR sets cache: 'reload' as an alternative to using the __WB_REVISION=... URL query parameter on the outgoing network requests used to populate the precache.

I also renamed some variables to clarify the distinction between cacheKey & url within the install() method.

The underlying precache keys still use the __WB_REVISION=... query parameters, as we continue to use those parameters as versioning metadata.

There's a slight breaking change in the updatedURLs & notUpdatedURLs values that are returned by install(): the previously would include __WB_REVISION query parameters, and now they won't. Since those return values are only used for logging/display purposes, this change is probably an improvement.

LGTM, with just one just comment that some of these variables would be even more clear with type declarations.
