`genai.vector.encode` doesn't allow for changing OpenAI API endpoints about neo4j HOT 1 OPEN

The GenAI plugin was written with Aura in mind, and as such we are only allowing known and controlled endpoints and options.

However, we have implemented the plugin with such thoughts of extension in mind, service loading vector embedding providers. Once we finalise the interfaces we will likely expose the interface publically such that on-prem enterprise customers can configure their custom embedding providers, which of course may be private and sensitive.

Due to many exposing an OpenAI-like API endpoint, we may expose an easier way to specifically configure such providers; such as a specific base class to extend, and/or a "simple" provider with a custom URI and pass everything on, etc, as things we are considering specifically for on-prem.

Until then, if it is necessary to use your internal custom endpoint, APOC Extended has https://neo4j.com/labs/apoc/5/ml/openai/ which can be used for this purpose in the mean time.
