[FR] Jupysql integration

## Description
It'd be great to see a tutorial or documentation of the 2 frameworks.
Probably a user working locally via a jupyter notebook and [jupysql](https://github.com/ploomber/jupysql) to query Pinot and perform EDA/modeling work.

## Motivation
Please provide the following for the desired feature or change:

A detailed explanation on querying via SQL.
Plotting via sql.
Using Pinot as part of Jupyter notebooks.

Happy to work on the PR!

No files or tests are named. Start by locating Pinot's existing SQL documentation and reviewing the Jupyter notebook and JupySQL integration requirements in the issue. Done means documenting SQL querying, SQL-based plotting, and using Pinot from a local Jupyter notebook for EDA or modeling.
