There are a number of cases of incorrect maven properties being used to control maven GAVs, e.g. ee.maven.version instead of full.maven.version, or project.version instead of ee|full.maven.version.

Further, there are three properties schemes used to control feature pack GAVs in the testsuite. Consolidate down to 1.

Finally, testsuite/layers-expansion should use the wildfly-standard-expansion-bom for dependencyManagement, not the default wildfly-standard-ee-bom.
