io.vertx.kotlin.circuitbreaker.io.vertx.circuitbreaker.CircuitBreaker

executeCommandAwait	`suspend fun <T> CircuitBreaker.executeCommandAwait(command: Handler<Future<T>>): T` Same as io.vertx.circuitbreaker.CircuitBreaker but using the circuit breaker default fallback.
executeCommandWithFallbackAwait	`suspend fun <T> CircuitBreaker.executeCommandWithFallbackAwait(command: Handler<Future<T>>, fallback: Function<Throwable, T>): T` Same as io.vertx.circuitbreaker.CircuitBreaker but using a callback.
