     * This method is complex, as there a number of things to account for:
     *
     * The `plugins` array can be set at construction, and/or it might be added to
     * to at any time before the strategy is used.
     *
     * At the time the strategy is used (i.e. during an `install` event), there
     * needs to be at least one plugin that implements `cacheWillUpdate` in the
     * array, other than `copyRedirectedCacheableResponsesPlugin`.
     *
     * - If this method is called and there are no suitable `cacheWillUpdate`
     * plugins, we need to add `defaultPrecacheCacheabilityPlugin`.
     *
     * - If this method is called and there is exactly one `cacheWillUpdate`, then
     * we don't have to do anything (this might be a previously added
     * `defaultPrecacheCacheabilityPlugin`, or it might be a custom plugin).
     *
     * - If this method is called and there is more than one `cacheWillUpdate`,
     * then we need to check if one is `defaultPrecacheCacheabilityPlugin`. If so,
     * we need to remove it. (This situation is unlikely, but it could happen if
     * the strategy is used multiple times, the first without a `cacheWillUpdate`,
     * and then later on after manually adding a custom `cacheWillUpdate`.)

     * See https://github.com/GoogleChrome/workbox/issues/2737 for more context.
