Subject: flink git commit: [maven] add module to force execution of Shade
 plugin

[maven] add module to force execution of Shade plugin

This ensures that all properties of the root pom are properly
resolved by running the Shade plugin. Thus, our root pom does not have
to depend on a Scala version just because it holds the Scala version
properties.

This closes #1755

+	This module is used a dependency in the root pom. It activates shading for all sub modules
+	through an include rule in the shading configuration. This assures that Maven always generates
+	an effective pom for all modules, i.e. get rid of Maven properties. In particular, this is needed
+	to define the Scala version property in the root pom but not let the root pom depend on Scala
+	and thus be suffixed along with all other modules.
