dmidecode >= 3.1 lower cases the system uuid which breaks folks who defined per node customization with upper case uuids

[Alex Schultz]

dmidecode >= 3.1 has normalized uuids to be lower case. The problem is that they may have been uppercase prior to this.

https://github.com/mirror/dmidecode/blob/master/NEWS#L2

This means anywhere we are using system UUIDs must be cause insensitive (handle both upper/lower). We currently use this in several places like in the per-node hieradata customizations and the os-net-config mappings file. This had previously broken ceph ansible in Bug 1814070

Anyone who does a minor update from CentOS7.5 with per-node customization to CentOS7.6 will have their per-node customization broken.

    Handle upper and lower case system uuids

    We need to be able to handle when system uuids are upper or lower case
    because newer versions of dmidecode have normalized to lower case. Users
    who were on CentOS/RHEL 7.5 and older may have per-node customizations
    with upper case which turn lowercase with an update to 7.6. This affects
    hieradata customizations as well as os-net-config mapping files. This
    change outputs both an upper and lowercase hieradata uuid file to handle
    the both versions of the UUID. Additionally this change normalizes the
    id comparison for os-net-config mappings to lower case.
