Description

Is your feature request related to a problem? Please describe.
Everytime I have to do a contourf I need to call it from matplotlib directly because locator argument is not passed from xarray.plot.contourf to matplotlib.

Describe the solution you'd like
Being ds a xarray.DataArray, I want to have the behaviour described here when passing locator = ticker.LogLocator() to ds.plot.contourf.

Describe alternatives you've considered
I usually have to do plt.contourf(ds.dim_0,ds.dim_1,ds.values,locator = ticker.LogLocator()).

Research direction

Start at xarray.plot.contourf and compare its arguments with matplotlib's contourf, focusing on the locator=ticker.LogLocator() example in the issue. Confirm how direct matplotlib calls handle the locator, then verify that the xarray plotting call accepts it and produces the same locator behavior.
