Create a Eureka discovery service

[Dev 958]

As we move to make more use of how Spring boot can take care of lots of the heavy lifting of running micro-services. By making use of the Spring-boot eureka discovery service, we will be able to simplify the code base around the config management and also make use of industry best practice.

If we do this work before moving to starting the palisade services via spring boot, then we can start by just registering the current services with Eureka and still using the existing config service to manage the config. But as we slowly move services over to the eureka discovery service we reduce the impact of the changes and eventually get to remove lots of plumbing code and focus more on the business logic.
