Add properties support for reactive circuit breaker

[ThomasVitale]

ReactiveResilience4JCircuitBreaker can now be configured through properties in the same way as its imperative counterpart.

Re-added documentation on how to work with configuration properties since the one added in #88 got lost.

Fixes gh-107
