[OK] Verified Admin APIs, Log Table related APIs and KV Table Related APIs
by running fluss-rust client integration test against docker image built
from source. One failure due to assertion failing from additional
*table.kv.format-version* field. This will be fixed on fluss-rust
integration test side.
