Extend the "vdb-codegen" plugin to generate a full Teiid Spring Boot project based on the VDB defined in YAML CR.

Currently the plugin already generates the `Application.java` and `DataSource.java` from a given DDL file, but when YAML file is supplied it should also generate the `pom.xml` and `application.properties` to be self-standing full TSB project as in this example https://github.com/teiid/teiid-spring-boot/tree/master/samples/vdb

The intent behind is to use this for the local building of the project for testing with VSCode Plugin. Based on how this works out, could also be used in Operator work flow.
