Unable to update app name

[denismakogon]

Create an app with name testapp and then try to update it.

curl -X PUT -d '{"app": {"name": "newapp"}}' localhost:8080/v1/apps/testapp

As response i get:

{"message":"App successfully updated","app":{"name":"testapp","config":null}}

And when i’m trying to list apps i get:

{"message":"Successfully listed applications","apps":[{"name":"testapp","config":null}]}

It appears that app name is immutable. So in order to fix it, following changes required:

• update docs to reflect immutability of an app name
• at API level return HTTP 403 with error message saying that app name is immutable
• update swagger doc to reflect real use case for HTTP PUT

In swagger there's an example:

{
  "app": {
    "name": "string",
    "config": {}
  }
}

But it doesn't have any effect, would be nice to have more useful example.
