Add the ability to connect to multiple pods using the jolokia api server

[lavocatt]

The only connection option we have right now is to connect to a single pod, it would be very practical if the API of the jolokia api server would allow us to connect to several pods at once and also request data from several pods at once.

What is expected for this issue:

• Create a corresponding issue on the jolokia api server upstream repo
• Implement and test the functionality over there
• Update the openapi yaml from the jolokia api server upstream repo once this is done
• Regenerate the code to have that available
