[Bug/Deprecation] explore.py is broken - might need to either be refactored or deprecated in favor of other methods to explore configs

[pkundurthy]

We do not see much utility for explore.py as a way to manage and explore meta data related to Chronon configs. Internally at airbnb, we are logging and displaying metadata via a process which loads data into a metastore, and a UI which queries and displays config details.

In addition, we see that explore.py is often broken when trying to do company-wide searches due various custom config settings:
