MultiClusterApplicationConfiguration Custom Resource Definition

The MultiClusterApplicationConfiguration custom resource is used to distribute core.oam.dev/v1alpha2/ApplicationConfiguration resources in a multicluster environment. Here is a sample MultiClusterApplicationConfiguration that specifies an ApplicationConfiguration resource to create on the cluster named managed1. To deploy an example application that demonstrates a MultiClusterApplicationConfiguration, see Multicluster Hello World Helidon.
