Description

Many existing JMX alerts use expressions like

        "jmx": {
            "property_list": [
              "Hadoop:service=NameNode,name=FSNamesystemState/CapacityUsed",
              "Hadoop:service=NameNode,name=FSNamesystemState/CapacityRemaining"
            ],
            "value": "{0}/({0} + {1}) * 100.0"
          }

JMXServerSide alert should be able to evaluate these expressions in a secure and safe way.
Supported operators: +,-,*,/,(,)
