VOL-4857 - add debugging

vars/installVoltctl.groovy
--------------------------
   o Display release vars in a single statement to avoid jenkins inserting 'echo' between each.

vars/setOnosLogLevels.groovy
vars/volthaDeploy.groovy
vars/volthaInfraDeploy.groovy
vars/volthaStackDeploy.groovy
-----------------------------
   o Added an ENTER/LEAVE printf to identify running script.
   o Consistent use of a shebang path.
   o Use pgrep to display port forwarding prior to termination
     + command pipeline can be shorted, let pgrep/pkill do heavy lifting.
   o Inlined temporary debugging to view output pipelines are acting on.
     + Debugging etcd:port=null and a few other anomolies.
