Describe the Feature

Currently module interface is designed to be used with VPC elasticsearch domains. Please add support for Public access domains.

Expected Behavior

Do not require variables definition for vpc and security groups required for VPC ES configuration. Also do not create related security group and other resources.

Use Case

Elasticsearch domain with Public access configuration.

Additional Context

In public access domains access can be controlled using IAM only or with SAML/Cognitio (if fine grained access control enabled). In the each of this case ES must know only ARN of lambda to provide access to cluster. In fine grained access control enabled case additional actions on ES configuration side may be required using lambda ARN.
