SimpleUpdate request should be validated before sending (POST with invalid payload is processing)

[ehaligow]

When I am sending following POST to SimpleUpdate (parameter Targets is missing):

intel@ubuntu:~/ODIM/build$ curl -X POST -k -u 'admin:Od!m12$4' https://odim.local.com:45000/redfish/v1/UpdateService/Actions/UpdateService.SimpleUpdate-d '{"ImageURI": "<URI_of_the_firmware_image>"}'| jq

 ],

}

I get response 202. Then, I send GET to TaskService with id given before, I get Critical. After that, after GET on TaskMonitor and learn that the property is missing.
