Feature request: Security user management via role variables

[Oddly]

Summary

It would be useful if the role could manage Elasticsearch security users (create custom users, set built-in user passwords) via role variables, so users don't have to write raw uri API calls in their playbooks.

Current situation

Users need to manually write ansible.builtin.uri tasks for each user/password change:

- name: Create logstash_internal user
  ansible.builtin.uri:
    url: "https://{{ inventory_hostname }}:9200/_security/user/logstash_internal"
    method: PUT
    user: elastic
    password: "{{ vault_pw }}"
    validate_certs: false
    force_basic_auth: true
    headers:
      Content-Type: application/json
    body:
      password: "{{ vault_logstash_internal_pw }}"
      roles: [logstash_writer, logstash_admin]
      full_name: Internal Logstash User
    body_format: json

This gets repetitive when managing multiple users and built-in passwords (kibana_system, logstash_system, beats_system, remote_monitoring_user).

Proposed solution

Add role variables like:

elasticsearch_users:
  - name: logstash_internal
    password: "{{ vault_logstash_internal_pw }}"
    roles: [logstash_writer, logstash_admin]
    full_name: Internal Logstash User

elasticsearch_builtin_passwords:
  kibana_system: "{{ vault_kibana_system_pw }}"
  logstash_system: "{{ vault_logstash_system_pw }}"
  beats_system: "{{ vault_beats_system_pw }}"
  remote_monitoring_user: "{{ vault_remote_monitoring_pw }}"

The role would handle the API calls internally with proper idempotency and no_log.
