Create Dockerfile variants to illustrate tomcat running on a specific version of Linux

[terrywbrady]

@pnbecker has embedded a sample Dockerfile in https://jira.duraspace.org/browse/DS-4160 to illustrate a bug in a specific version of Linux. I recommend that we implement something like this with the following conventions.

• follow the installation directories used in the DSpace/DSpace Dockerfile
• rely on an external postgres instance rather than embedding this locally
• add this Dockerfile to this repo in the Dockerfiles directory

The goal should be to make the image produced from this dockerfile to be swap-able with the dspace/dspace images referenced in the DSpace Docker compose files.
