[FEATURE] Update MKS cluster to the LATEST_PATCH

[rverchere]

Description

When using the ovh_cloud_project_kube, I can update it to the next minor version, i.e 1.28 to 1.29.

But there is no way to update the cluster to the last patch version.

Affected Resource(s) and/or Data Source(s)

• ovh_cloud_project_kube

Potential Terraform Configuration

I see here

terraform-provider-ovh/ovh/resource_cloud_project_kube.go

Line 612 in d7186ad

Strategy: "NEXT_MINOR",

that the code allow only NEXT_MINOR when upgrading, but the strategy allows LATEST_PATCH.

When performing a terraform state, the is_up_to_dateis false, so we know there is a new version:

❯ terraform state show module.kubernetes-ovh-cluster.ovh_cloud_project_kube.k8s_cluster

    }

    timeouts {

        delete = "30m"
        update = "1h"
    }
}

❯ terraform plan -out="tfplan.out"

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed.

Remarks

Note that I want to manage myself the update of the cluster, so keep update_policy to NEVER_UPDATE.
