    Fix to prevent mishandling of OS_REGION_NAME

    With the Subcloud Rename Feature, a mechanism was introduced in
    dcmanager, when the deployment file is uploaded, to modify the
    OS_REGION_NAME prior to send it to the subcloud, required for
    the installation of the Deployment.

    Doing this manipulation of the deployment file on the dcmanager
    site generates confusion for the handling of the required
    OS_REGION_NAME parameter.

    This commit revers the change to handle the deployment file from
    the dcmanager, passing the responsability to the Deployment.

    Closes-Bug: 2036632

    Test Plan:

    PASS: Add a new subcloud and validate the content of
    deployment_config.yaml inside of subcloud. The value of
    OS_REGION_NAME parameter should be equal to the same parameter
    taken from environment variables.
