[AMBARI-23276] Maven cleanup

[adoroszlai]

What changes were proposed in this pull request?

Clean up pom.xml files somewhat:

• Copy version and some other files in the process-resources lifecycle phase, not in generate-resources or generate-test-resources.
• Remove some version declarations from ambari-agent and ambari-server that are already (or should be) declared in the parent POM.
• Major cleanup in ambari-funtest: its pom.xml was copied from ambari-server, but it really depends only on some libraries and ambari-server. There is no src/main/resources in ambari-funtest, either.
• Explicitly declare dependency on Guava in ambari-server.
• Get rid of unnecessary dependency: ambari-serviceadvisor -> maven-assembly-plugin. This brought a bunch of unnecessary jars to ambari-server's bundle:

How was this patch tested?

• Full build from scratch:

  $ mvn -B -fae -Del.log=WARN -DskipTests clean package
  ...
  [INFO] BUILD SUCCESS
  [INFO] ------------------------------------------------------------------------
  [INFO] Total time: 11:21 min
  

• Built rpms for ambari-server and ambari-agent, installed locally. Verified that the jars listed above are not present in /usr/lib/ambari-server.
• Installed ZooKeeper cluster via blueprints, added HDFS via UI.
• Ran ambari-serviceadvisor with inputs from a previous run:

  export PYTHONPATH=/usr/lib/ambari-agent/lib
  export CLASSPATH=$(echo /usr/lib/ambari-server/*jar | sed 's/ /:/g')
  cd /var/run/ambari-server/stack-recommendations/1
  java org.apache.ambari.serviceadvisor.ServiceAdvisor recommend-configurations hosts.json services.json OUT ERR
