DATAGO-59496: Make docker run for user without root access

[gregmeldrum]

What is the purpose of this change?

Two changes:

1. Change docker base image to eclipse-terumin to be the same as the rest of the microservices (this addresses https://sol-jira.atlassian.net/browse/DATAGO-59217)
2. Make the docker container run for users without root access in docker

How was this change implemented?

1. The base image was updated in the buildEventManagementAgentDocker.sh script to manually set the base image to eclipse-terumin.
2. The base image directory was removed since it's no longer used.
3. The Docker uses /opt/ema as it's new working directory since it can be used by docker containers running without root access.

How was this change tested?

Docker container was manually built and testing in the following scenarios:

1. Run a scan, connected to EP with docker running with root user
2. Run a scan, connected to EP with docker running as non root user
3. Run a scan and download, not connected to EP with docker running with root user
4. Run a scan and download, not connected to EP with docker running as non root user

Is there anything the reviewers should focus on/be aware of?
