* Introduce new operation with suffix "IfExists" for all
string and numeric condition operations;
* An operation with "IfExists" suffix specifies the following: if the condition key
is present in the context of the request, process the key as specified in the policy.
If the key is not present, evaluate the condition element as true;
* Change the signature for interface method `Property()`: since it returns two
values - the second indicates whether the property exists;
* This also means that original condition operations for string and number comparison
is slightly changed: if property doesn't exist, then the condition is not evaluated.

It can be false if the first targets allows operation and the last one
returns NoRuleFound.

So, it's sunday evening and I am sitting on-call trying to debug strange
node behaviour. It took me 3 whole minutes to understand the code being
changed: it accumulates bools in slices, even though no slice is needed;
it uses subtle condition from the first loop to make decision in the
second one, and finally it uses named return values.
In this commit we remove the slice and the second loop, because why not.

Make it possible to execute fuzz tests with different backend, such as
go-fuzz which supports coverage collection.

* Make `ListMorphRuleChains` methods use `commonclient.ReadIteratorItems`.
* Introduce `ContractStorageActor` interface.
* Iterators are used because listing by `ListChainsByPrefix` may cause
stack overflow from neo-go side (len(items) > 1024).

We must be able to read s3 multipart object from storage
(to find out the parts it consists of)
to fully delete such multipart object

because of tombstone must be created (it's a put operation)
