Fix incopatibility of 5.0 version with Kubernetess Java Client

[vladimir-bukhtoyarov]

In the scope of upcoming 5.0 version async functionality was removed for non-distributed buckets as useless(because local buckets is extremely fast and there is no reason to await results of operations in async way). But in the result of the investigation of Bucket4j's dependencies, I found that Kubernetes Java Client uses async buckets in the non-distributed environment. The reason to do that is simple, they just want to consume tokens unconditionally(independently of the fact if limitation violated or not) and just track the amount of violation.

To fix compatibility with Bucket4j 5.0 it needs to do the following:

• Add unconditionalConsume method to the API.
• Prepare a pull request to the kernetes-client/java.
