Issue details

When creating an eks cluster with support for eks fargate, it's creating a fargate profile to the default namespace.

		eksCluster, err := eks.NewCluster(ctx, "MyCluster", &eks.ClusterArgs{
			Name:              "MyCluster",
			Fargate:            pulumi.Bool(true),
                       .....
               }

it's problematic when you need a custom fargate profile like that :

namespaceName := "customNamespace"

namespace, err := corev1.NewNamespace(ctx, namespaceName, &corev1.NamespaceArgs{
		Metadata: &metav1.ObjectMetaArgs{
			Name: pulumi.String("namespaceName"),
			Labels: pulumi.StringMap{
                                // custom pod labels for alb 
				"elbv2.k8s.aws/pod-readiness-gate-inject": pulumi.String("enabled"),
			},
		},
	}, pulumi.Provider(eksProvider))


customFargateProfile, err := fargate.NewFargateProfile(ctx, "MyCustomFargateProfile", &fargate.FargateProfileArgs{
		ClusterName:         eksCluster.EksCluster.Name(),
		FargateProfileName:  pulumi.String("MyCustomFargateProfile"),
		PodExecutionRoleArn: executionRole.Arn,  // custom execution role here
		SubnetIds:           subnets,   
		Selectors: fargate.FargateProfileSelectorArray{
                        // custom list of namespaces here
			&fargate.FargateProfileSelectorArgs{
				Namespace: pulumi.String("kube-system"),
			},
			&fargate.FargateProfileSelectorArgs{
				Namespace: pulumi.String("default"),
			},
			&fargate.FargateProfileSelectorArgs{
				Namespace: pulumi.String("newrelic"),
			},
			&fargate.FargateProfileSelectorArgs{
				Namespace: pulumi.String("amazon-cloudwatch"),
			},
			&fargate.FargateProfileSelectorArgs{
				Namespace: pulumi.String(namespaceName),
			},
		},
                // custom tags
		Tags: customTags,
	}, pulumi.Provider(eksProvider), pulumi.DependsOn([]pulumi.Resource{namespace}))

it's would be great to allow users to pass their custom fargate profile directly

		eksCluster, err := eks.NewCluster(ctx, "MyCluster", &eks.ClusterArgs{
			Name:              "MyCluster",
			Fargate:            pulumi.Bool(true),
                        FargateProfileArn:  customFargateProfile.Arn()
                       .....
               }

Or just a way to disable the creation of the default fargate profile

		eksCluster, err := eks.NewCluster(ctx, "MyCluster", &eks.ClusterArgs{
			Name:              "MyCluster",
			Fargate:            pulumi.Bool(true),
                        CreateFargateProfile: pulumi.Bool(false),
                       .....
               }

Thanks for filing this issue @dbouclier; I'll add this to our backlog.

The cluster component supports providing a custom fargate profile: https://www.pulumi.com/registry/packages/eks/api-docs/cluster/#fargate_nodejs.

You can either pass a boolean - if it's true a default fargate profile will be created - or you pass a FargateProfile object.
