Is your feature request related to a problem?

For the dataset groupby and data array groupby I often end up with a groups that have too few observations to be useful for statistics of plotting and have to go through and remove those bins before analysis or plotting.

Describe the solution you'd like

I would love to have a keyword that would let users remove bins below a certain number of observations. I usually don't want bins with 1-10 observations when plotting or doing statistics. I was thinking min_observation for each method and then just filter out bins below that number of observations.

Describe alternatives you've considered

I recognize that users can go through and filter out and skip bins with too few values during plotting or analysi, but this might be convenient.

Additional context

I have not contributed before and was thinking this might be an appropriately sized project to contribute back to xarray, but I wanted to see if I was missing something about why this isn't an option before I worked on it.

It seems like the code would be limited to the groupby code and the groupby tests.
