feat: Support overlay generation with remote refs

Add option to generate overlay using remote (i.e. github.com/kuadrant/dns-operator/config/..) or local configuration (i.e. ./config) ``` make generate-cluster-overlay DEPLOYMENT_COUNT=2 CLUSTER_COUNT=2 USE_REMOTE_CONFIG=false ``` Signed-off-by: Michael Nairn <[email protected]>
