Is it possible to avoid `Close()` + `Reopen()` for a clean Database which is opened for only TP service?

[zhanglei1949]

Currently we require any opened database to be closed and reopened before service TP queries.

neug/tools/python_bind/src/py_database.cc

Line 124 in 29d7c29

database->Close();

However, for those users which simply open a large database for serving TP queries, the close and reopen is not necessary.
Could we provide some interface on python client like

from neug import load_and_serve

server = load_and_serve(
    db_path="/path/to/database",
    host="127.0.0.1",
    port=10000,
    blocking=False,
    max_thread_num=0,
    thread_num=0,
    buffer_strategy="M_FULL",
)

print(server.endpoint)
server.stop()

Which returns a Server handle.

class DatabaseServer:
    @property
    def endpoint(self):
        ...

    def stop(self):
        ...

    def close(self):
        ...

    def __enter__(self):
        return self

    def __exit__(self, exc_type, exc, tb):
        self.close()

We could also let Database.serve() return the same handle.

Reason: The issue requests a new Python client API (load_and_serve, DatabaseServer handle) for the Python binding, which falls squarely under the Node.js/Python binding umbrella #418.
