Plugin dependencies should not be managed

[pkocandr]

Dependencies of a plugin cannot be managed by dependencyManagement in Maven. But it happened, that an internal redhat version was returned as a dependency of public version from Maven Central, while this was not declared in its pom. To be concrete one of the paths was:

org.jboss.teiid.quickstart:drools-integration:3.0.0.redhat-63-8
has parent org.jboss.teiid.quickstart:teiid-quickstart-parent:3.0.0.redhat-63-8 
uses plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 
depends on (scope compile) org.apache.openjpa:openjpa:2.2.0 
depends on (scope compile) com.sun.xml.bind:jaxb-impl:2.2.5.redhat-9 
has parent com.sun.xml.bind:jaxb-project:2.2.5.redhat-9 
embeds relaxngcc:relaxngcc:1.12-redhat-2 
depends on (scope compile) net.java.dev.msv:msv-core:2011.1-redhat-2

The problem is that openjpa 2.2.0 specifies a dependency on jaxb-imple 2.0.5, not 2.2.5.redhat-9. The graph was computed with build-requires preset, default mutator and patcher-ids "dependency-plugin" and "dist-pom".

When we reach a plugin we should probably replace the selected mutator by NOOP and use it down the dependency graph.
