Application attribute in webhook JSON

[gmarsay]

Summary

Following issue #5879... I would like the attributes of an application defined on the TTS console to appear in the JSON received via the webhook.

Current Situation

Following your integration of PR #7524, I notice that the application attributes are not sent by the webhooks.

Why do we need this? Who uses it, and when?

In our case we place the attributes at the application level so as not to have to repeat the same information on all end-devices. Currently we are forced to make requests on the API after receiving a webhook, to retrieve these attributes.

Proposed Implementation

Add the application attributes to the webhook uplink (and other) JSON
