Changes made within examples/em-server-multi-tier-cronjob to use and run server images created by new CI in e-mission-server.

CHANGEME left in docker-compose.yml for port number so that user/tester can think about what they need for their purposes themselves.

Removed the use of a script that reinstalled conda while saving the config copying. Moved where supplemental scripts get copied into.

Change starting image from one hosted by Andrew to Shankari. Tested and works.
