Add HttpResponseCacheTest as a CTS test
Moving HttpResponseCacheTest.java from
frameworks/base/core/tests/coretests/src/android/net/http
to
cts/tests/tests/net/src/android/net/http/cts
And making it work in the CTS runner by setting
temp directory permissions and making sure the
cache is initialized.
