aws-qa-appsync-opensearch: Make congnito user pool id as optional input

[saikatak]

Describe the feature

Currently the module aws-qa-appsync-opensearch authenticates GraphQL APIs using cognito user as primary authentication mode and IAM as additional authentication mode.

This module is requiring cognito user pool id as mandatory input parameter making the consumer of this module create user pool explicitly and provide the user pool id which would take away the simpleness of the module. Making cognito user pool id as optional(and falling back to IAM authentication if no user pool is provided) would help to avoid the additional effort required to create user pool out side of this module.

Use Case

When using this module for simple and sample POCs , we are required to create a cognito user pool and user pool application client and then use it along with this module.

Proposed Solution

Make cognito user pool id as optional and fall back to IAM authentication if no cognito user pool is is passed
