input-group on wrapping every component

[batusai513]

I'm having this issue where every component in the form is getting the input-group class, and that class is just for elements with prefix or sufix (or both), and when using bootstrap, the style is messed up.

We originally had it as you described but this caused a lot of issues with fields with a prefix or suffix inside of a datagrid or table since they have different box properties depending on whether they are in an input-group or not. To resolve this we always put them in an input-group and added some CSS to make it look better. See https://github.com/formio/react-formio/blob/master/formio.css#L3-L28

This may not be the best solution so let me know if you have any thoughts on it.
