pom specifies incorrect groupId for commons dependencies

pom.xml specifies commons depencencies as follows:
<dependency>
<groupId>commons-collections</groupId>
<artifactId>commons-collections</artifactId>
<version>3.2.1</version>
</dependency>

Commons packages have been migrated to use correct groupId of org.apache.commons so these dependencies should be changed accordingly. We caught this when rebuilding commons packages using maven for Fedora rawhide and our build system was unable to find dependencies because of this.
