Code Sample, a copy-pastable example if possible

python da.resample(time='MS').sum('time')

Problem description

Pandas has deprecated the TimeGrouper class (https://github.com/pandas-dev/pandas/issues/16747) and that warning has started popping out during xarray resample operations. We can make this go away quite easily. (I'll submit a PR shortly).
