Add Grid.boundary

See original GitHub issue

How about having xgcm.set_options(boundary="extend") or similar to save quite a lot of typing?

Good idea. But one might not want to set these globally, since someone might be working with multiple different Grid objects in one session.

Instead, they could be attached to a grid. For example

grid = Grid(ds, coords={'X': {'center': 'x_c', 'left': 'x_g'},
                        'Y': {'center': 'y_c', 'left': 'y_g'}},
           periodic=False, boundary={'X': 'extend', 'Y: 'fill'})

Then every time you did grid.diff(data, 'X') it would apply the specified boundary condition.

The path to implementing this would be to attach a new attribute to Axis objects

and then pass that through the Grid constructor.
