Recreate examples

Why

Fixes #1388

What

Create new example which should be more user-friendly. It works for the latest "non-beta" release.

Check examples/README.md.

I also consider to try adding Grafana Loki as a separate PR.

Tests

Automated test via make all and a GitHub workflow to test it in CI.

LGTM. Just minor Qs and suggestions.

I agree that the proposed changes makes it simpler for users to execute and instrument the sample app.
But, I strongly feel we should have one of ASP.NET Core based project as a part of the example. It will help us debug and validate our changes. Shall we keep current AspNetCoreMvc project along with proposed changes in this PR?

@rajkumar-rangaraj Server is an ASP.NET Core app (minimal Web API). Do you prefer to change it to use the ASP.NET Core Web Host? We can also add another HTTP service and they communicate using MassTransit. Do you have any preference?

Personally, I would lean towards refactoring the existing Service application.

We may also merge this PR as it is and you can create a refactor PR if you find it easier.

It will help us debug and validate our changes

I would rather use test applications for it 😉

I glossed over the yml files for the docker-compose and all the config, but everything else looks good to me 👍🏼
