Decouple web validator deployment from core validator releases

[davidgamez]

Describe the problem

The web validator service and UI components are tied to the gtfs releases. This introduces an unnecessary blocker to release the service and UI faster.

Proposed solution

• Restructure maven projects to allow the web project to be released independently from core projects. This will imply using Maven dependencies to the core module from the Maven central rather than the parent module.
• Allow the deployment of the web layer to be independent of core releases. This means that production deployment will always use the latest released core libraries.
