Point users to Couchbase initializer in Getting started

This could be a useful thing to add in our Getting started section, maybe in a new page/section?

Couchbase Initializer helps new users get up and running with a Couchbase SDK quickly.
It's a one-stop-shop to generate simple, fully functional projects that can be run and/or imported into IDEs with very little information provided upfront.

See Spring Initializer for an idea of what the dev team is aiming for:

Here is the RFC for Couchbase Initializer:

NOTE: This is currently still being developed, but worth keeping an eye on when ready for users. It's probably not needed for SDK 3.5, but worth discussing with PMs.
