Description

We need a simple and stable API for the OAP server to verify the server API version, this API version could be different from the BanyanDB version, but it keeps the compatibility information and patch version.

The response version should be like

1. major version number. OAP will rely on this to check compatibility.
2. mini version number. BanyanDB maintains this for internal usage, and OAP will output this when the database is connected in the booting stage.

BanyanDB should have a document to list all releases(from 0.8)' API versions.
