Kuadrant/dns-operator

AI Summary: Implement a feature for the Kuadrant DNS Operator to load controller configuration from a ConfigMap. This ConfigMap will override default values for controller flags, enabling flexible deployment scenarios and supporting future 'modes' for the operator, such as cluster-aware DNSRecord delegation. The implementation should involve reading the ConfigMap, parsing its data into environment variables, and integrating these variables into the controller's initialization.

AI Summary: Update all GitHub Actions workflows that use the `actions/setup-go` action to fetch the Go version from the project's `go.mod` file instead of hardcoding it. This ensures the workflow always uses the correct Go version specified in the project.

AI Summary: Update the provided DNS record examples to be provider-agnostic, handle multi-owner scenarios, and include a README with usage instructions. This involves fixing issues with existing AWS-specific configurations, adding examples for other providers, and creating comprehensive documentation.
