Deploy Spring music on acceptance

[georgethebeatle]

Background

As the service binding functionality in Korifi is getting more complex in preparation for managed services support and higher compliance with the v3 spec we need to have a better guarantee of service consumptiom working properly. As discussed in this PR's comments we can use the spring music app to validate that servicebinding.io bindings are working correctly.

Actions to take

• Deploy spring music on the acceptance cluster
• Perform a quick test to see if it is workng correctly as part of the pipeline

Implementation details

• We can easily deploy a postgres intance on k8s using this helm chart
• We could extend the smoke tests to deploy spring music and bind psql as a user provided instance (or provide a separate script or test suite that does that)
