STEPS TO REPRODUCE

Run a playbook with the following task:

    - name: Provision DB 
      community.aws.rds_instance:
        availability_zone: us-east-2a
        engine: aurora
        engine_version: 5.6.10a
        allow_major_version_upgrade: no
        auto_minor_version_upgrade: yes
        db_cluster_identifier: cilogon-registry-cluster-01-dev
        db_instance_class: db.t3.small
        db_instance_identifier: cilogon-registry-dev
        db_parameter_group_name: cilogon-aurora-mysql-5-6-parameter-group-dev
        state: present
        region: us-east-2

Wait for the database to be created.

Run the same playbook with the same task. The task shows

TASK [Provision DB] *********************************************************************
[WARNING]: Module did not set no_log for force_update_password
changed: [localhost]

even though nothing has changed.

EXPECTED RESULTS

After the database is created and no changes are made to the task I expect running the task to show

ok: [localhost]

ACTUAL RESULTS

TASK [Provision DB] *********************************************************************
[WARNING]: Module did not set no_log for force_update_password
changed: [localhost]

I also verified that the issue happens with 2.10.0 and 2.11.0.dev0

This issue should have been fixed by #1002 which is available in release 3.3.0
