Install callbacks

Adjust servers trigger an install callback when a user opens an app for the first time after install.

The callback parameter for install callbacks is install_callback.

Important:
If you're using Branded Links or Universal Links, you must prefix the callback parameter with adj_. Use adj_install_callback for the install_callback parameter.
