Align app labels with kubernetes recommendations

[etsauer]

What does this PR do?

Align with kubernetes recommended app labels

How should this be tested?

Deploy basic-spring-boot pipeline, and check to make sure all resulting resources have the following labels on them:

      app.kubernetes.io/name:
      app.kubernetes.io/instance:
      app.kubernetes.io/component:
      app.kubernetes.io/part-of:
      app.kubernetes.io/managed-by:

Before we merge, we might want to have a discussion about how we assign values to these.

Is there a relevant Issue open for this?

related to #119
