Wrong groupId for ojdbc8 dependency

The pom.xml files currently include the following dependency:

<dependency>
  <groupId>com.oracle</groupId>
  <artifactId>ojdbc8</artifactId>
</dependency>

However, ojdbc8 is no longer available at com.oracle. The new location is com.oracle.database.jdbc. Therefore, the dependency (in all pom.xml files that have it), should read something like:

<dependency>
  <groupId>com.oracle.database.jdbc</groupId>
  <artifactId>ojdbc8</artifactId>
</dependency>
