Forks the Lucene data structure into a class called PackedArray that can be serialised using Elasticsearch streams.

Currently, Cuckoo filters use Lucene structures to hold in memory arrays of packed ints. This is problematic when we move to Lucene 9.0 as those classes have been heavily modified, In addition we use Lucene Input/output API to serialise / deserialise the data structure which will break as well as Lucene is changing the API endianness.
Therefore, this PR forks the Lucene data structure into a class called PackedArray. The main change is that this class will be using Elasticsearch streams to serialise / deserialise, therefore we remove the dependency in Lucene's endianness. WE are still using lucene PackedInts to handle backwards compatibility.
We added a ESRestTestCase that can trigger the creation of Cuckoo filters and run in a mixed cluster in order to check backwards compatibility.
