Standardize component defaults across Aviary

[jkirk5]

Desired capability or behavior.

With many of our components, default values for inputs/outputs are provided that come from a variety of sources - maybe there were old GASP defaults, generally reasonable values, or values that match a particular aircraft model. This is not desired for a variety of reasons.

• These defaults can differ from what is specified in the variable metadata, which confuses which value is the "true" default
• It can make it difficult to realize that a value was never set/specified
• It perpetuates bad coding practices, where data should be kept separate from code
  among other things. A standard default (such as 0 or 1) should be enforced for all component inputs/outputs. Options may want similar treatment but may require additional thought before implementing.
