Define a truly minimal working example

[agardnerIT]

Related to #59 , what would a minimal working example really look like? Probably not a no-op example but I imagine reading a boolean flag from a JSON or text file.

Reasons:

• 1. Quick startup times and useful on minimal infrastructure
• 2. Gets across the concepts whilst remaining vendor agnostic
• 3. Serves as a "lead-in" to more complex or vendor specific scenarios (that will be created and maintained by the vendor)

I think minimal and minimal while meaningful/useful might be different things.

I think the demo https://github.com/open-feature/playground/pull/59 is pretty close to the minimum while being useful. To showcase even the actual benefits of OpenFeature, I'd argue you need:

• a couple features to toggle
• the ability to switch feature flag providers

Once you have these, implementing a lot of other (and much more interesting) features doesn't take much more work):

• OTel integration
• flagd provider integration
• demo hooks (validation, etc)

I think once the playground is completely dockerized, it will satisfy all the reasons above with almost zero effort required to run: docker compose up. This is one of the primary goals of #59 .

The most recent update to the playground should provide a nice balance between minimal and meaningful. Please reopen if you disagree and provide suggestions for what could be improved.
