Option to add Storage Options through the config instead of having to create a custom Storage Bean

[a1shadows]

Is your feature request related to a problem? Please describe. Currently in order to customize the Storage Bean for things like retries and timeouts, the only way seems to be to initialize a custom bean like so

@Bean
    public Storage storage() {
        RetrySettings retrySettings = RetrySettings.newBuilder()
                .setInitialRetryDelay(Duration.parse(initialRetryDelay))
                .setRetryDelayMultiplier(retryDelayMultiplier)
                .setMaxRetryDelay(Duration.parse(maxRetryDelay))
                .setMaxAttempts(maxAttempts)
                .setTotalTimeout(Duration.parse(totalTimeout))
                .build();

        return StorageOptions.newBuilder()
                .setRetrySettings(retrySettings)
                .build()
                .getService();
    }

Describe the solution you'd like It would be super convenient to have the ability to provide these configurations in the application.properties file itself to be picked up during auto-configuration of the bean. For eg.

gcp:
  storage:
    retry:
      initial-retry-delay: 1s
      retry-delay-multiplier: 2.0
      max-retry-delay: 10s
      max-attempts: 5
      total-timeout: 1m

I would love to help implement something like this
