Bump FE pom to Java 8 source/target version
Our dependency on Hadoop 3 means we already required Java 8. This just
fixes the pom so we are compiling to Java 8 classes. This will also
allow us to start using some Java 8 features like lambdas for more
concise code.

> we achieved lazy consensus that we should deprecate support for Java 7 and
> should require Java 8 going forward.
> We should introduce a pre-compile check for the minimum supported Java
> version. This will help us prevent opaque errors during compilation from
