operator sdk and maistra controller dependencies issue

Customer is updating a custom operarator with the new operator-sdk version 1.12.0 compatible with k8s 1.21 and Openshift 4.8 and there's an issue importing the maistra types.

Current custom operator libraries:

Golang repository with an custom operator that uses and manages maistra types (ServiceMeshControlPlane, ServiceMeshMember, ServiceMeshMemberRoll) with the following go dependencies related to your maistra (https://github.com/maistra/istio-operator/tree/maistra-2.0) and operator sdk (https://github.com/operator-framework/operator-sdk/tree/v0.18.0) repositories

• operator-sdk : 0.18.0
• maistra 2.0
• controller-runtime: v0.6.0

Upgrade custom operator:

Upgrade to operator-sdk to 1.12.0 (https://github.com/operator-framework/operator-sdk/tree/v1.12.0) and maistra 2.3 (https://github.com/maistra/istio-operator/tree/maistra-2.3.0), but the operator sdk uses controller dependencies "controller-runtime: v0.9.2" and maistra 2.3 "controller-runtime: v0.6.3"

So, the problem here is importing "maistra_v1_apis - github.com/maistra/istio-operator/pkg/apis/maistra/v1" because find incompatibles versions about the controller-runtime.
