fix(eks): add tag update support for eks cluster

[mrlikl]

Issue # (if applicable)

Closes #19388

Reason for this change

Adding tag/untag for eks cluster post its creation

Description of changes

Added API calls tagResource and untagResource in Cluster resource handler to handle tag changes

Description of how you validated changes

Have tested the changes by first deploying a cluster with below config:

const vpc = ec2.Vpc.fromLookup(stack, 'Vpc', { isDefault: true });
new eks.Cluster(stack, 'Cluster', {
  vpc,
  ...getClusterVersionConfig(stack, eks.KubernetesVersion.V1_29),
  defaultCapacity: 0,
 tags: {
    foo: 'bar',
  },
});

TestCase - 1 Update to add one more tag

new eks.Cluster(stack, 'Cluster', {
  vpc,
  ...getClusterVersionConfig(stack, eks.KubernetesVersion.V1_29),
  defaultCapacity: 0,
  tags: {
    foo: 'bar',
   hello: "world"
  },
});

Logs -

        "updateAccess": false,
        "replaceRole": false,
        "updateVersion": false,

}

{
  clientName: 'EKSClient',
  commandName: 'TagResourceCommand',
  input: {
    resourceArn: 'arn:aws:eks:us-east-1:xxxxx:cluster/Cluster9EE0221C-f0d60e8e0bf14fb5896ade518b5bbc15',
    tags: { hello: 'world' }
  },
  output: {},
  metadata: {}
}

TestCase2 - Add, update and remove at the same time

new eks.Cluster(stack, 'Cluster', {
  vpc,
  ...getClusterVersionConfig(stack, eks.KubernetesVersion.V1_29),
  defaultCapacity: 0,
  tags: {
    hello: 'world1',
    foobar: 'baz',
  },
  endpointAccess: eks.EndpointAccess.PUBLIC,
  vpcSubnets: [{ subnetType: ec2.SubnetType.PUBLIC }],
});

{
  clientName: 'EKSClient',
  commandName: 'TagResourceCommand',
  input: {
    resourceArn: 'arn:aws:eks:us-east-1:xxxxx:cluster/Cluster9EE0221C-f0d60e8e0bf14fb5896ade518b5bbc15',
    tags: { foobar: 'baz', hello: 'world1' }
  },
  output: {},
  metadata: {}
}

{
  clientName: 'EKSClient',
  commandName: 'UntagResourceCommand',
  input: {
    resourceArn: 'arn:aws:eks:us-east-1:xxxxx:cluster/Cluster9EE0221C-f0d60e8e0bf14fb5896ade518b5bbc15',
    tagKeys: [ 'foo' ]
  },
  output: {},
  metadata: {}
}

TestCase - 3 Remove all tags

new eks.Cluster(stack, 'Cluster', {
  vpc,
  ...getClusterVersionConfig(stack, eks.KubernetesVersion.V1_29),
  defaultCapacity: 0,
  endpointAccess: eks.EndpointAccess.PUBLIC,
  vpcSubnets: [{ subnetType: ec2.SubnetType.PUBLIC }],
});

{
  clientName: 'EKSClient',
  commandName: 'UntagResourceCommand',
  input: {
    resourceArn: 'arn:aws:eks:us-east-1:xxxxx:cluster/Cluster9EE0221C-f0d60e8e0bf14fb5896ade518b5bbc15',
    tagKeys: [ 'foobar', 'hello' ]
  },
  output: {},
  metadata: {}
