onem2m-simple-config:iplugin-cfg-put rpc shouldn t allow to use non existing plugin-name or plugin-instance

Following request shouldn`t work because of plugin-name aaa which doesn`t exist. only Onem2mExample should work in there

POST
http://localhost:8181/restconf/operations/onem2m-simple-config:iplugin-cfg-put

{
"input": {
"plugin-name": "aaa",
"instance-name": "default",
"plugin-simple-config" : {
"key-val-list" : [

{ "cfg-key": "port", "cfg-val": "1000" }

]
}
}
}

neither should this one because of it`s instance name aaa
