Different google-cloud-java artifacts depends on different versions of the libraries, breaking build any enforcer projects

[emmanuelbernard]

Hey,

I'm winged by @glaforge on having a Hibernate OGM dialect. Here is the error I get from an enforcer based maven module (we use enforcer because I'm told it's the right thing to do :) ).

The module dependency definition is

 <dependency>
            <groupId>com.google.cloud</groupId>
            <artifactId>google-cloud-spanner</artifactId>
            <version>0.10.0-beta</version>
