Support for lifecycle hooks

[eytan-avisror]

We should add support for adding lifecycle hooks via instance-manager.

Example:

spec:
  eks:
    configuration:
      lifecycleHooks:
      - name: my-hook
        transition: autoscaling:EC2_INSTANCE_TERMINATING
        defaultResult: Abandon
        heartbeatTimeout: 300
        queueARN: <notification-arn>
        roleARN: <role-arn>

This would need to make a very simple call put-lifecycle-hook to add it after the ASG is created.
