Deprecate and remove the Server Log View.

The Server Log View was originally designed to allow a custom "Error Log" to be filled with information that wasn't just "errors" but more like tracing what the server adapter was doing.

In it's original form, it held all status warnings and errors, and users never saw them. Eventually, we started also sending the status objects to the official Error Log, so users may see them. Once that happened, the Server Log view became completely redundant. It's only benefits were that it occasionally over-logged stuff that wasn't appropriate to send to the main error log... but it's API / extension points were kinda ugly, and it overall isn't very useful any longer.

Also, other server adapters have requested we remove the action at least, for their server types, since they never use the Server Log.
