Adds fugue integration

[ahuang11]

Closes #1097

Surprisingly easy to set up! cc: @goodwanghan

import xarray as xr
import hvplot.pandas
import fugue.api as fa
from hvplot.fugue import _parse_hvplot

ds = xr.tutorial.open_dataset("air_temperature")
df = ds.groupby("time.season").mean().mean("lon").to_dataframe().reset_index()

fa.fugue_sql(
    """
    OUTPUT df USING hvplot:points(
        x="lat",
        y="air",
        by="season",
        size=100,
        opts={"width": 500, "height": 500}
    )
    """
)

Also, not sure if we should change this:

        assert_or_throw(len(dfs) == 1, FugueWorkflowError("not single input"))

hvplot + panel can probably dump extra dfs in tabs, but I just followed this example
