Introduce transformer `cacheKey`

Summary:public

At the moment, the packager's cache can only be broken by changing packager's `package.json` version,by supplying a different `cacheKey` or by updating the `mtime` of the transformer. We need to add support for breaking the cache key when a plugin the transformer use gets updated. To do so, lets introduce a property on the transformer, namely `cacheKey`.
