Add note about empty fields and null values for API responses

Browse Source 
Add a note the global swagger docs about some fields not showing

null values for complicated field types that swagger-go has a hard time
with.

[NO TESTS NEEDED]

// NOTE: some fields in the API response JSON are set as omitempty, which means that
// if there is no value set for them, they will not show up in the API response. This

// NOTE: due to the limitations of [go-swagger](https://github.com/go-swagger/go-swagger),
// some field values that have a complex type show up as null in the docs as well as in the
// API responses. This is because the zero value for the field type is null. The field
// description in the docs will state what type the field is expected to be for such cases.
