Vector support

[meistermeier]

This issue might be a placeholder for various Vector type related features:

1. Conversion between Spring Data Commons Vector type and a Neo4j Java driver Vector type.
   At the moment there is no explicit type in the driver to convert to. Creating a converter for this yet, does only make it easier for people already storing double[] to Neo4j but not for "real" (special) vector types.

2. Make use of build in vector searches
   The topic that will be built on top of the vector type will be support for vector search in repositories.

Note

at the moment this is on-hold
