Support swaggerignore field tag in structs for fields that should not be shown in swagger docs

[larrycinnabar]

It's allowed to specify format, binding, swaggertype, etc tags to the struct fields.

But it's very useful to just ignore the field for swagger docs. It's a basic practice when you have fields in the model that are filled internally, not from frontend. So documentation just do not need to know about them

json:"-" not work ?

[larrycinnabar]

json:"-" will make swagger to ignore the field, right. But I do need the json tag on that field.
Json tag - is json tag, swagger tags - are just about documentation.
