[Feature] - Implement JarCheck for the config server

[salim-1997]

Is your feature request related to a problem? Please describe
The gradle plugin JarCheck is currently implemented in the core sub-project. In our project JarCheck assures that the jar files of the 3rd party libraries, that are used in our core sub-project, are using java 8.
We want to add JarCheck to the config server to avoid java compatibility problem while interacting with other compenents.

Describe the solution you'd like
Currently JarCheck is implemented locally as a seperate class inside the core sub-project. We want to either:

1. Create a jarCheck class globally for the whole project and connect it with the gradle build files of the core and config server sub-projects. This might be possible by configuring the gradle settings in the project.
2. Implement JarCheck as a plugin in a separate project and connect it to the build files of core and config server.
3. Implement JarCheck as a remote plugin and connect it with core and config server.
