Short-circuit xr.concat to blindly concatenate data and coords without fancy checks

[raj-magesh]

Is there a way to short-circuit xr.concat's fancy checks for alignment, etc. to just concatenate all the data and coords of the input DataArrays?

I find that it's much slower to use xr.concat than np.concatenate. I could try concatenating the data and each coord separately and creating a new DataArray; is that the recommended approach?
