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 "Acept:applicaton/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 contenst 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
