4.1 Forwarder Documentation about documentation

[dulanism]

Just making a note here that I'm making a few minor edits to what will be the old enterprise data forwarder. Really just the name, and the graphic which is out of place.

Hi @dulanism, I have made some notes here about the thinking on documentation changes for the 4.1 Forwarder in case you have time to work on it in the next weeks. Development on the Forwarder will continue, and some parts might change. I will be back in June 1, and will check back in then! :)

@dulanism @danotorrey please find below the essential functional diff between Cloud and On-Prem:

Aspect	Cloud	On-Prem
Server-side Service Configuration	The configuration is still done via the config file. Nothing has changed here. Except one minor thing: a new property to configure TLS private key password was introduced, but I believe it should not be reflected in the public documentation.	To avoid 1) having the Forwarder server-side services running by default and 2) restarting the server after making changes in the config file, it was decided to migrate away from the config file and to introduce a new Input type, which is supposed to facilitate Forwarder server-side service configuration and lifecycle management. The name for the new Input is Forwarder. The legacy one was renamed to Cluster-to-Cluster forwarder. This change entailed certain modifications in the Wizard: 1) Now the Wizard must verify if there is at least one running input 2) Populate the Forwarder (client) configuration snippet according to the Input's config values. So in other words one additional step was introduced to make sure that there is a running server-side service to connect to. See screenshots below. NOTE that some server-side configuration properties are still to be provided via the config file (not expected to change frequently): grpc_graceful_shutdown_timeout, grpc_max_message_size, heartbeat_timeout_interval, forwarder_user (see https://github.com/Graylog2/graylog-plugin-cloud/wiki/Forwarder#forwarder-configuration-properties-server-side). Not sure if it should be a part of the public document.
Menu Layout	Nothing should change here.	The Forwarder menu item resides under Enterprise
