Is your feature request related to a problem?

I am experiencing some issues with the way coordinates are padded. Currently the coordinates are padded according to the mode parameter passed to pad() here. For my particular issue I want to be able to have different modes for the data, but effectively pin the mode that is used to pad the coordinate values.

A simple example: ```python import xarray as xr import numpy as np

da = xr.DataArray([1,2,3], dims=['x'], coords={'x':[4,5,6]}) da ```

If I pad with constant python da.pad(x=(0,1), mode='constant') I get this: which is the coordinate padding I need.

But if I pad with wrap: python da.pad(x=(0,1), mode='wrap') which gives me repeated coordinate values

Describe the solution you'd like

I would like to be able to do something like this:

python da.pad(x=(0,1), mode='wrap', coord_pad_mode='constant') and get something like this

Since #3596 internally already defines coord_pad_mode it should be easy enough to expose this to the user?

Possibly related (but I think not incompatible with the changes propsed here?): #3868

Happy to work with @TomNicholas on a PR, but wanted to get some feedback/comments first.
