> It is common that you want to filter out or transform properties before they are applied to a target, for example you may want to filter out by prefix and in camel-k we do something like that:
> {code}
> public static int bindProperties(CamelContext context, Properties properties, Object target, String prefix) {
>         final AtomicInteger count = new AtomicInteger();
>         properties.entrySet().stream()
>             .filter(entry -> entry.getKey() instanceof String)
>             .filter(entry -> entry.getValue() != null)
>             .filter(entry -> ((String)entry.getKey()).startsWith(prefix))
>             .forEach(entry -> {
>                     final String key = ((String)entry.getKey()).substring(prefix.length());
>                     final Object val = entry.getValue();
>                     try {
>                         if (PropertyBindingSupport.bindProperty(context, target, key, val)) {
>                             count.incrementAndGet();
>                         }
>                     } catch (Exception ex) {
>                         throw new RuntimeException(ex);
>                     }
>                 }
>             );
>         return count.get();
>     }
> {code}
> Would be nice to have a support for filtering out of the box
