Replace Predicate and Iterables with Cactoos equivalent

[filfreire]

I'm working on yegor256/rultor#1199

How do we replace with the equivalent Cactoos classes the following Guava classes/calls:

RqUser.java (Iterables.any(...) and Predicate):

final boolean granted;
// ...
final Identity identity = this.identity();
granted = Iterables.any(
    readers,
    new Predicate<String>() {
        @Override
        public boolean apply(final String input) {
            return !identity.equals(Identity.ANONYMOUS)
                && input.trim().equals(identity.urn());
        }
    }
);

(edit: removed second question into new issue #476)

@yegor256 please, pay attention to this issue

@filfreire I would kindly ask you to submit one problem per ticket, to avoid confusion and noise. Here, I will answer the first question only. You should use Or:

final boolean granted;
// ...
final Identity identity = this.identity();
granted = new Or(
  r -> !identity.equals(Identity.ANONYMOUS) && r.trim().equals(identity.urn()),
  readers
).value();

@yegor256 thanks, Moved second question into a new issue #476. I'm closing this issue, seems to work with your suggestion.
