[Feature] Allow defining customized IAM inline policy name

[guessi]

What feature/behavior/change do you want?

With current design, the inline policy name will always be Policy1. For example, if user define ClusterConfig as follow,

addons:
  - name: vpc-cni
    version: latest
    podIdentityAssociations:
    - namespace: kube-system
      serviceAccountName: aws-node
      # Copied from https://docs.aws.amazon.com/eks/latest/userguide/cni-iam-role.html#cni-iam-role-create-ipv6-policy
      permissionPolicy:
        Version: "2012-10-17"
        Statement:
        - Effect: Allow
          Action:
          - "ec2:AssignIpv6Addresses"
          - "ec2:DescribeInstances"
          - "ec2:DescribeTags"
          - "ec2:DescribeNetworkInterfaces"
          - "ec2:DescribeInstanceTypes"
          Resource: '*'
        - Effect: Allow
          Action:
          - "ec2:CreateTags"
          Resource: 'arn:aws:ec2:*:*:network-interface/*'

It would get

Because inside the code, it hard-coded as Policy1

	if len(rs.attachPolicy) != 0 {
	rs.template.AttachPolicy("Policy1", roleRef, rs.attachPolicy)
	}

Why do you want this feature?

Allow user to define the inline policy name (or custom defined suffix/prefix).
