feat: one json column to rule them all

[gitcommitshow]

RudderStack discards events with more than 200 properties as "Bad Event". This results in droping genuine events sometimes. Also these properties are flattened by default in warehouse, resulting in too many columns sometimes reaching the upper limit of columns in warehouses. A usual challenge faced in collecting data from unstructured or semi-structured webhook data with lots of nested values.

This user transformation is a solution to these challenges.
It enables your data pipeline to store all event properties as single json data type column.
Here, we first move event.properties to context.properties and then set jsonPaths option to track.context.proprerties. This instructs RudderStack to not flatten context.proprerties of track events and store that as json data type column.
