allow forwarding setup to specify Malcolm connection information in one place (vs. three)

[mmguero]

When configuring forwarding for Hedgehog to Malcolm, right now you have to do filebeat, arkime and "miscbeat" in three different steps.

It would make more sense to ask for the the information once and then set it in all three places, as it almost 100% will always be the same.

I could still leave the option to configure them individually, but I should add an option to configure all of the forwarding in one spot.
