Comments:
@rajibmitra found another in `pandas/tests/scalar/timestamp/test_unary_ops.py::TestTimestampUnaryOps::test_round_dst_border_nonexistent`, if you could update that too.
`pandas/tests/series/test_datetime_values.py::TestSeriesDatetimeValues::test_dt_round_tz_nonexistent` as well
and `pandas/tests/test_config.py::TestConfig::test_deprecate_option`
@rajibmitra make sure you merge master
@jreback merged my master. thanks.  
@TomAugspurger  will do those changes in couple of minutes , give me some time. Thanks. 
@rajibmitra I'm going to push a few more fixups here.
sorry , got busy with other stuff, sure @TomAugspurger 
No worries.
Merging this on green, since it's failing other builds.
lgtm.
