Create an experimental extensions package

[samarpan-b]

How about we create an extensions folder within this monorepo, where we can keep all our experimental extensions or related POC implementation before they can be published over npm separately ?

Some conditions for extensions here

• They all will be private here
• They will have sample MVP implementation with complete documentation and list of pending items
• Basic TCs and examples, wherever possible.

This is taking inspiration from LB4 experimental extensions package here -> https://github.com/strongloop/loopback-next/tree/master/extensions

Would like to suggest creating an extension for sequelize ORM using loopback.
