rpc hang sometimes after oslo try to reconnect to the servers

[Mehdi Abaakouk]

Hi,

When we use ceilometer with kombu (rabbitmq), sometimes when the server gone and ceilometer try to reconnect to it, the connection can hang.

This is because, ceilometer monkeypatch only socket and not select, or when kombu detect monkeypatching on the socket module, it assume the select is monkeypatched too and use the real select.select on a eventlet socket, and hang.

Ceilometer must enable monkeypatch for select too.

Cheers

    Enable monkeypatch for select module

    is gone and ceilometer tries to reconnect to it, the connection can hang.
