Add support for configuring environment variables for operators
This change allows users to specify custom environment variables for operator containers through the operatorOverrides field in the OpenStack CR. Changes: - Add Env field to ContainerSpec in the API types - Implement mergeEnvVars() to merge custom environment variables with defaults - Update SetOverrides() to apply environment variable overrides - Enhance operator deployment templates to support both Value and ValueFrom for environment variables (supporting secrets, configmaps, and field refs) Usage example: apiVersion: operator.openstack.org/v1beta1 kind: OpenStack metadata: name: openstack spec: operatorOverrides: - name: infra controllerManager: env: - name: SOME_ENV_VAR value: "some-value" Co-Authored-By: Claude <noreply@anthropic.com>
