unable to fetch the MAC table for few devices where it is throwing error with body structure is not correct

[Ziabatcha]

Observing " Writing operation into Elastic Search Failed : body structure is not correct from element" in docker logs, whereas for the same node we are able to retrieve the MAC table from Controller.

Docker Logs:

500 - Error: Writing operation into Elastic Search Failed : body structure is not correct from element (I time) 529253447 Resend the request....
500 - Error: Writing operation into Elastic Search Failed : body structure is not correct from element (II time) 529253447 --> Dropped from Sliding Window

ODL output:

            {
                "mac-address": "8c:68:3a:01:ed:df",

in the callback PromptForUpdatingMacTableFromDeviceCausesWritingIntoElasticSearch there is a check which control that the body message is complete, in particular it should contain:

• a body
• the body should contain a field "mac-address"
• the field "mc-address" should be an array with length > 0
• the array should contain "mount-name" field.

If one of this conditions are not present the application exit with the message reported in the bug
