Remove all uses of defaultProps on functional components

[nylon22]

🐛 Bug report

Current Behavior

There are several functional components inside this repo that make use of defaultProps. Ex. https://github.com/Availity/availity-react/blob/master/packages/breadcrumbs/src/Breadcrumbs.js#L54

Which causes this warning from React:

Warning: Breadcrumbs: Support for defaultProps will be removed from function components in a future major release. Use JavaScript default parameters instead.

Expected behavior

default JavaScript parameters should be used in favor of React defaultProps

Suggested solution(s)

default JavaScript parameters should be used in favor of React defaultProps
