Add an Excess Fuel Output to Dashboard for FLOPS Missions

Desired capability or behavior.

It is currently possible to execute and optimize an aircraft sizing mission where the Aircraft.Fuel.TOTAL_CAPACITY < MIssion.Design.FUEL_MASS. Legacy FLOPS was also able to do this, and had a variable 'EXSFUL' (Excess Fuel) that would show up in the output file -ve and with a warning message to the user if this condition was triggered.
I think we should add this to aviary, printing a message to the command line and adding a flag in the dashboard to show that although the optimization problem was solved the results may not be representative of a physical aircraft.

Aviary has no capability to set the Aircraft.Fuel.TOTAL_CAPACITY based on the fuel required for the design mission. This would be a nice to have feature as currently it is very easy to not specify enough inputs in the .csv for the fuel_capacity_group subsystems which will result in undefined circular references:

It is currently important to set either total_capacity or (fuselage_fuel_capacity and auxiliary_fuel_capacity) in the input file, otherwise these circular references will occur.

The ability to feedback Mission.Design.FUEL_MASS into Aircraft.Fuel.TOTAL_CAPACITY would replicate the IFUFU=1 FLOPS behavior.
