Kuryr-libnetwork docker will has ssl error in multi-threads

[Liping Mao]

Environment:
kuryr-libetwork runs in docker, neutron is under https.

Problem:
1. when kuryr-libnetwork container runs in process 2, thread 2. it will has the following ssl error:

docker: Error response from daemon: failed to create endpoint nervous_shaw on network limao_kuryr1: NetworkDriver.CreateEndpoint: SSL exception connecting to https://ci92hf-neutron.qa.webex.com:443/v2.0/networks.json?tags=kuryr.net.uuid.lh%3Aa2e3b4bb50095c9d6323d41b35cc04a7%2Ckuryr.net.uuid.uh%3Aebe1bb7e21db844ea24a12ea80c43eff: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:1754).

2. If it runs in process 2, thread 1 (or process 1, thread 1). It works fine.
