DATAJDBC-246 - Configured Travis CI build for JDK 9-11.

Upgraded the dependency-plugin.
Configured matrix build for travis, allowing the JDK 11 build to fail.
The failure should go away once the Spring Framework version we use include the fix for SPR-17093.
Removed Jacoco from the build for JDK 10+.
