SDD: Hard size condenser systems

Add hard size capability for Cooling towers based on nominal capacity
method.  Currently sizing fan power and design air flowrate using
calculations dependent on SDD provided capacity.  SDD provided fan power
and air flowrate result in EnergyPlus failure because a UA cannot be
calculated.  The combination of values provided by current SDD instances
appear to be unrealistic.
SDD: Set maximum reheat flow fraction

Also set ConstantMinimumAirFlowFraction to 0.
Additional AWSProvider updates:
total session uptime
total session instances
terminate session and remove key pair
verify terminated instances

Still needs much more testing, slight reorganization
Added region/serverInstanceType/workerInstanceType to AWSSettings
