Allows to identify chart changes before actually running lint or install commands. This can be useful in the following cases: * In a CI setup where kind clusters are spun up on the fly, this makes it possible to decide whether a cluster is necessary at all. A PR may only contain changes that are not relevant to any charts. * By knowing upfront which charts have changed, it is possible to load a per-chart CI configuration which would allows us to determine the number of nodes needed in a kind cluster. For most charts, one node is enough, but in certain scenarios, especially for StatefulSets, we may want to test with pod anti-affinity where replicas have to be spread across multiple nodes.
