Support for Spring Boot DevTools Restarter

[AB-xdev]

As discussed with @zdenek-jonas @JohannesRabauer @hg-ms.

It would be great to have support for the Spring Boot DevTools Restarter.
This way it would be a lot easier to e.g. modify UI/Endpoints because you no longer have to constantly restart your application manually if you want to "see" your changes.

The following points appeared while we discussed this:

• There is a basic implementation for SDES
  • It stops the storage when a restart occurs (Listener for ContextClosedEvent)
  • This works for a very basic project (one entity with a few simple fields)
  • This might just work inside SDES, as SDES uses IDs
  • Might be sufficient for most basic users of EclipseStore?
• There are some concerns about handling objects e.g. when using multiple classloaders or what happens when a object is referenced in some part that is not reloaded
  @zdenek-jonas @hg-ms can describe them likely in more detail as they have more insight :)
• Further research should likely be done before coming to any conclusions
