   -  CDN in a Box
   
   ## Current behavior:
   <!-- Describe how the bug manifests -->
   Accompanying the June 3 CentOS 8.4.2105 release, `hwloc-libs` and other libraries updated, breaking compatibility with the 2018 `trafficserver-7.1.4-2.el7.x86_64` RPM that we use for the caches in the CDN in a Box. Attempting to run `trafficserver` manually results in a shared library error being logged to `/var/log/trafficserver/traffic_server.stderr`:
   
   ```
   /usr/bin/traffic_cop: error while loading shared libraries: libhwloc.so.5: cannot open shared object file: No such file or directory
   ```
   
   This breaks the *CDN-in-a-Box CI* GitHub Actions workflow.
   
   ## Expected behavior:
   <!-- Describe what the behavior would be without the bug -->
   Traffic Server should run without any shared library issues.
   
   ## Minimal reproduction of the problem with instructions:
   <!--
   If the current behavior is a bug, please provide the *STEPS TO REPRODUCE* and
   include the applicable TC version.
   -->
   Run `traffic_cop` to see the shared library error:
   ```shell
   docker-compose build --no-cache --parallel edge
   docker-compose run --rm edge traffic_cop
   ```
   
   ## Anything else:

   *   Installing `hwloc-libs-1.11.9-3.el8.x86_64` (previous version) instead of `hwloc-libs-2.2.0-1.el8.x86_64` (current version) is not an option, the package is not found:
       ```
       [user@computer trafficcontrol]$ docker run --rm centos:8.3.2011 dnf install hwloc-libs-1.11.9-3.el8.x86_64
       CentOS Linux 8 - AppStream                      7.1 MB/s | 7.4 MB     00:01
       CentOS Linux 8 - BaseOS                         3.0 MB/s | 2.6 MB     00:00
       CentOS Linux 8 - Extras                          30 kB/s | 9.6 kB     00:00
       No match for argument: hwloc-libs-1.11.9-3.el8.x86_64
       Error: Unable to find a match: hwloc-libs-1.11.9-3.el8.x86_64
       ```
   
   *   The Dockerfile already [symlinks disparate library versions](https://github.com/apache/trafficcontrol/blob/5ad059f0af/infrastructure/cdn-in-a-box/cache/Dockerfile#L59-L68) for `libtcl`, `libncursesw`, and `libtinfo`. If `libhwloc.so.15` is symlinked to `libhwloc.so.5` and `traffic_cop` is started,
   
       ```shell
       ln -s libhwloc.so.15 /usr/lib64/libhwloc.so.5
       traffic_cop --stdout
       ```
   
       then `traffic_server` crashes (let's not pursue the CentOS 7 ATS 7 RPM on CentOS 8 any further).
