This does not change the mockito library to use mockito-extended in
FrameworksNetTests, but changes the tests so that they would pass if
built against that library.
This is useful to run FrameworksNetTests in a common test suite with
other tests that use mockito-extended, for example a common connectivity
coverage test target.
The change includes increasing the test timeout in
ConnectivityServiceTest, as mockito-extended can have performance impact
(~3 times on hwasan builds). This change does not make tests run slower
in the current FrameworksNetTests suite though.
