Remove unused Interface com.openexchange.apps.manifests.ServerConfigMatche rServiceServerConfigMatcherService during refactoring of com.openexchange.apps.manifests.json.AllAction. The AllAction was split into two parts:
- A standalone com.openexchange.serverconfig.ServerConfigService that can be used by all components
- A slimmed down AllAction that uses the ServerConfigService to deliver a server config to clients.

External/custom implementations of this interface (if existing) will break
