OCI environment variables are not recognized

[devwebcl]

Issue Report

I am using Ansible collections with API authentication, so I have a ~/.oci/config file. However, when I try to set up environment variables such as OCI_USER_ID and OCI_REGION, they are not honored at runtime, and the values from the config file are always used instead.

A clear and concise description of what the issue is.

Expected behavior

new values set through environment variables

Environment

• OS version:
  Linux

• Ansible version:

  ansible 2.9.27
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/opc/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.6/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.6.8 (default, Nov 16 2023, 04:13:44) [GCC 8.5.0 20210514 (Red Hat 8.5.0-20.0.1)]

Ansible playbook to reproduce the issue

export OCI_TENANCY=ocid1.tenancy.oc1..xxx
export OCI_USER_ID=ocid1.user.oc1..xxx
export OCI_USER_FINGERPRINT=xxx
export OCI_USER_KEY_FILE=/path...
export OCI_REGION=region...

this is a simple task just to check underneath the new values are recognized:

---
- name: Get a specific instance
  oracle.oci.oci_compute_instance_facts:
    # required
    instance_id: "ocid1.instance.oc1.REGION.XXXX"
