Show metadata descriptions conditionally based on feature type

[DanielRyanSmith]

Some of the important metadata fields, like "Feature Name" and "Summary", require drastically different guidance based on feature type (specifically deprecation) to capture correct inputs.

Once the feature is created, the fields should be simple enough to capture an alternative description for each of the fields in the metadata section. However, we display metadata fields at the time of creation, so we would need to conditionally display these descriptions based on the feature type as the user is selecting the feature type. This should be simple enough by displaying only the feature type radio button selection on the page, and then fading the other fields into view based on the feature type selection. This also has the added benefit of displaying the importance of the user selecting the correct feature type.
