module: idrac_redfish_info
short_description: Gather PowerEdge server information through iDRAC using Redfish APIs
description:
  - Builds Redfish URIs locally and sends them to remote iDRAC controllers to
    get information back.
  - For use with Dell EMC iDRAC operations that require Redfish OEM extensions.
  - This module was called C(idrac_redfish_facts) before Ansible 2.9, returning C(ansible_facts).
    Note that the M(community.general.idrac_redfish_info) module no longer returns C(ansible_facts)!
