BREAKING TESTING CHANGES

If you don't mock Long Running Operations (LRO) in your tests, then these
changes will not affect you.

With the addition of new methods to support starting Long Running Operations
(LRO) synchronously and awaiting their completion separately, the overload set
for the preexisting LRO methods have been expanded. Uses of EXPECT_CALL that
do not have matchers for the arguments will be ambiguous. To quickly remedy this
change instances of EXPECT_CALL(*mock, Method) to
EXPECT_CALL(*mock, Method(::testing::_)).
