add support for JVM monitoring

add support for JVM monitoring

in common-functions.sh
    - function get_features:
      add decanter-collector-jmx,decanter-appender-elasticsearch to the variable
      to allow the proper decanter feature installation
    - the new function add_jvm_support():
      allow executing of scripts
       .../test/csit/scripts/set_elasticsearch_attribute_short.sh (or ...long.sh)
       .../test/csit/scripts/set_jvm_common_attribute.sh
      for allow  decanter & elasticsearch configuration & installation
      and eliminate the need to list them
      in scriptplans files (in the folder integration/test/csit/scriptplans)
      This function is called from scripts
      integration-configure-clustering.sh and integration-deploy-controller-run-test.sh
    - function get_test_suites:
      added python call to generate plots to eliminate the need to list
      integration/test/csit/suites/integration/Create_JVM_Plots.robot
      in testplans (in the folder integration/test/csit/testplans)

jenkins job parameters

    - update description of parameter CONTROLLERFEATURES
    - create the new parameter ELASTICSEARCHATTRIBUTE

    ELASTICSEARCHATTRIBUTE will serve for indicating how to set
    elasticsearch attribute while calling of respective shell script from
    releng/builder/jjb/integration/common-functions.sh function run_plan

get rid of explicit mentions of decantor related features in current yaml files

elasticsearch-attribute
- set default to short in jjb/defaults.yaml
- set value to long in all projects which contain the longevity functionality
- new job parameter ELASTICSEARCHATTRIBUTE inserted to the integration-controller-parameters macro in jjb/integration/integration-macros.yaml
- adding setting of the new parameter to each template (reffering the integration-csit-parameters macro) in jjb/integration/integration-templates.yaml
- adding setting of the new parameter to the template refering the integration-controller-parameters macro in jjb/integration/distribution/distribution-templates.yaml
