Plugin to make multiple ipa calls via one remote procedure call 

To run this code in the lite-server 

curl   -H "Content-Type:application/json"          -H "Accept:application/json" -H "Accept-Language:en"        --negotiate -u :          --cacert /etc/ipa/ca.crt           -d  @batch_request.json -X POST       http://localhost:8888/ipa/json 

where the contents of the file batch_request.json follow the below example 

{"method":"batch","params":[[ 

        {"method":"group_find","params":[[],{}]}, 

        {"method":"user_find","params":[[],{"whoami":"true","all":"true"}]}, 

        {"method":"user_show","params":[["admin"],{"all":true}]} 

        ],{}],"id":1} 

The format of the response is nested the same way.  At the top you will see 

  "error": null, 

    "id": 1, 

    "result": { 

        "count": 3, 

            "results": [ 

And then a nested response for each IPA command method sent in the request
