Changes

• add new flag to payout and start command for address on which lb fee will be sent

@mpetrun5 you can review this code, but we shouldn't merge this yet as I need to do some additional manual testing to be on the safe side.

I'm a bit scared of this actually haha. I guess we should:

• add confirmation that user is sure that it wan't to payout everything
• maybe when starting give big fat warning if lb payout address is same as lb tresury address or maybe don't let it start with that config?

@mpetrun5 @mpetrunic If the user wants the entire balance to be treated as reward then an additional address for lb fees must be provided. Additionally, the user is prompted to confirm this external address once more as seen in the example below

Example

Prompt example:

Keep in mind we shouldn't have prompt on starting of load balancer (it would make it unusable to be run as service)

Now prompt is only shown on the manual payout, not on starting LB
