[FEATURE] Integrate Jvector engine as another vector engine of choice

[sam-herman]

Is your feature request related to a problem?
Currently k-NN plugin supports 3 engines, Nmslib, Faiss and Lucene.
In this change I would like to integrate JVector as another engine of choice.
There are a number of reasons to doing so:

1. Disk ANN - JVector is capable to perform search without loading the entire index into RAM.
2. Compatibility - JVector is compatible with Cassandra. Which allows to more easily transfer vector encoded data from Cassandra to OpenSearch and vice versa.

What solution would you like?
Introduce JVector into K-NN plugin as another supported engine.

What alternatives have you considered?
