Start thinking about leveraging aspire-samples existing tests as part of our overall test coverage

[joperezr]

As discussed offline, we should begin to think about how to use aspire-samples and their tests as part of our overall testing story in Aspire. This includes the following:

• Enabling a daily run which updates the version of aspire used by the samples and ensure that the projects still compile, as well as ensuring that they can run their tests successfully.
• Ensuring we have some gates to detect any breaking changes needed when trying to upgrade from version to version. Ideally, we'd like to validate that updating from a stable version to the nightly version would be possible in a non-breaking way.

Assigning @DamianEdwards for now as he has started to do some thinking here.
