/**
* Stops all programs that are passed into the data. The data is an array of JSON objects
* where each object must contain the following three elements: appId, programType, and programId
* (flow name, service name, etc.).
* <p>
* Example input:
* <pre><code>
* [{"appId": "App1", "programType": "Service", "programId": "Service1"},
* {"appId": "App1", "programType": "Mapreduce", "programId": "MapReduce2"},
* {"appId": "App2", "programType": "Flow", "programId": "Flow1"}]
* </code></pre>
* </p><p>
* The response will be an array of JsonObjects each of which will contain the three input parameters
* as well as a "statusCode" field which maps to the status code for the data in that JsonObjects.
* </p><p>
* If an error occurs in the input (for the example above, App2 does not exist), then all JsonObjects for which the
* parameters have a valid status will have the status field but all JsonObjects for which the parameters do not have
* a valid status will have an error message and statusCode.
* </p><p>
* For example, if there is no App2 in the data above, then the response would be 200 OK with following possible data:
* </p>
* <pre><code>
* [{"appId": "App1", "programType": "Service", "programId": "Service1", "statusCode": 200},
* {"appId": "App1", "programType": "Mapreduce", "programId": "Mapreduce2", "statusCode": 200},
* {"appId":"App2", "programType":"Flow", "programId":"Flow1", "statusCode":404, "error": "App: App2 not found"}]
* </code></pre>
