Added aspire sample

[JerryNixon]

This is a simple sample that demonstrates how to use DAB in Aspire.

I will add it to our docs/quick-starts when this is merged.

Please note there is no /src code change, just /samples.

We really need to add this to our tests in order to avoid requiring the full suite of integration tests when /samples is updated. In fact, there are many paths in this repo that should be set up to allow pull requests to skip integration tests. Please consider.

@Aniruddh25 I've opened a new pull request, #2990, to work on those changes. Once the pull request is ready, I'll request review from you.
