[BEAM-1819] Key should be available in @OnTimer methods

Review comment:
@mxm, upon debugging, I noticed that timer.getKey() returns String, Integer,
as well as ByteBuffer. That's why when I changed the method signature,
DoFnOperatorTest failed with ClassCastException. And I have added an instanceof
check
