example: add time-series models with statsmodels

[jsamantaucd]

Feature request I have implemented and tested a feature that trains a time series model - ARIMA and serves it using BentoML's custom runner to make predictions.

Motivation I believe it would be a nice guide to someone exploring time series models with custom runner implementation for models like ARIMA.

Others: This feature was tested on Bentoml v1.2.16

Hi @xianml, as per your suggestion I have created the same arima model example using bentoml >=1.2, please help to review. Regards!

Hi @jsamantaucd We are preparing to restructure the examples and do not accept new framework-specific examples.

You can make it in a standalone repository and we can link it in our README, thanks.

Hi @frostming and @jianshen92, thank you for your valuable feedback, I incorporated everything in the current stats model example and created a standalone repository here: https://github.com/jsamantaucd/BentoStatsmodel, please kindly link it in your README, thanks!
