Include a simple tilt setup to validate its usefulness for us

Describe the solution you'd like Include a simple tilt setup to validate its usefulness for us. A simple Tiltfile and instructions to use it.

What is the added value? First we validate if it would make things easier at all. Later we see if this could make the developer experience smoother :) . We can attract more contributions like this.

Give us examples of the outcome

Stumbled upon this example project: https://github.com/tilt-dev/memcached-operator

So it seems that using tilt for developing operators is something that happens and makes sense.
