Pandas doesn't require matplotlib, koalas shouldn't either.

Pandas will use matplotlib if it's available, but matplotlib isn't a dependency if Pandas.

We're deploying batch-processing applications for use in data pipelines, which will never try to plot anything and don't need matplotlib.

We are required to scan our deployments with Veracode, and Veracode raises many issues with matplotlib and matplotlib's dependencies.

We can work around this by replacing databricks.koalas.plot.KoalasPlotAccessor with a unittest.mock.MagicMock, but that's evil. :)

Koalas shouldn't require matplotlib.

Yeah, I think we can keep it as an optional dependency

Fixed in #2029
