Project version passthrough

[brianjahnke]

The version of the dataspace connector has to be manually set in multiple project files. By doing so there is a high risk that the version is not updated in all files. This could lead to major problems down the line since the version is used for runtime descriptions of the connector.

I suggest that the version is only set once in the pom.xml. The other locations may pull the information from the pom.

There are currently (at least) three locations where the version has to be set manually:

1. pom.xml
2. ConnectorApplication.java
3. config.json
