[eolivelli]

Summary:

• add support for "service=milvus" as "vector-database" resource
• implement the QueryStepDatasource interface for Milvus

This is part 1, missing parts:

• make the sample app work on "docker run"
• test with the SaaS service
• add docs

it seems that the Milvus SDK imports lots of dependencies, we should fix this or build a dedicate nar file
