Make it easier to exclude fields in deep object hierarchy

[neibarbosa]

Hello there,

First of all, thanks for awesome work.

I am upgrading easy-random from 3.7.0 to 5.0.0 and I have a scenario where I want to generate a random bean but excluding a field deep down in the object hierarchy. Supposing that I have the structure below:

public class Person {
    private Address address;
    private String name;
    ...
}

public class Address {
    private Street street;
    ...
}

public class Street {
    private String name;
    ...
}

I want to generate a random instance of Person but excluding their street name. In 3.7.0 I could use nextObject(Person.class, "street.name"), reflecting the path of fields using a dot-separated string as excluded field.

RandomTestUtils.nextRandom(Person.class, "name"));

> [name=<null>,address=[street=[name=nHfelv]]]

RandomTestUtils.nextRandom(Person.class, "address.street.name"));

> [name=dumIVTe,address=[street=[name=<null>]]]

In 5.0.0, according to #349, I understand I should implement an ExclusionPolicy.

However it is very hard to implement a policy that complies to my case without having access to the stack of RandomizationContextStackItem and to method getFieldFullName both in RandomizationContext. ExclusionPolicy gives me a handle to a RandomizerContext, not a RandomizationContext.

Is there an easy way to emulate the old behavior using version 5.0.0?
