Code Sample, a copy-pastable example if possible

This code ```python da = xr.DataArray(np.random.randn(10, 20, 8))

hdl = da.plot(col_wrap = 4, row='dim_2') ```

yields this image:

Then, running this: ``` def mark_point(color='k'): plt.plot(10, 4, 'ko')

hdl.map(mark_point) ```

gives

Problem description

Calling facetgrid.map calls facetgrid._finalize_grid which calls tight_layout which screws up the colorbar (eventually).

Quoting https://matplotlib.org/users/tight_layout_guide.html#colorbar

If you create a colorbar with the colorbar() command, the created colorbar is an instance of Axes, not Subplot, so tight_layout does not work. With Matplotlib v1.1, you may create a colorbar as a subplot using the gridspec.

So the solution could involve writing a custom colorbar function.
