Besides reading attributes the jolokia2 agent should be able to invoke operations from custom Mbeans through the JMX.

We would like to see operations to be captured from invoked actions

Current behaviour supports only read requests and attributes ie: curl http://localhost:10012/jolokia/read/java.lang:type=Memory | python -m json.tool

I would like to have also operations supported for custom Mbeans(for our applications) created in Spring.boot. An example is: http://localhost:10162/jolokia/exec/org.springframework.boot:type=Endpoint,name=Health/health/ | python -m json.tool While I can see the result in command line I cannot capture it with telegraf

Research direction: Review the existing jolokia2 input plugin code to understand how attribute reads are implemented. Then, extend the plugin to support operation invocations by adding a configuration for allowed operations and modifying the HTTP request to use /exec endpoints.
