Adding a method to the NetworkContext to clear the HTTP cache. The
implementation in the network service duplicates some of the code from
content::StoragePartitionHttpCacheDataRemover.

Changed the BrowsingDataRemoverBrowserTest.Cache test to work with the
network service. Since we do not want to expose more cache states
(such as cache size) for tests, we rely on reloading pages after
stopping the embedded server to test the page is available in the
cache.
