[Impact]
Unable to enable TLS termination of any endpoints for OpenStack with Python 3.7.

[Test Case]
sudo apt install python3-eventlet
python3 << EOF
import eventlet
eventlet.monkey_patch()

import socket
import ssl

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
wrappedSocket = ssl.wrap_socket(sock)
EOF

Traceback (most recent call last):
  File "<stdin>", line 8, in <module>
  File "/usr/lib/python3/dist-packages/eventlet/green/ssl.py", line 403, in wrap_socket
    return GreenSSLSocket(sock, *a, **kw)
  File "/usr/lib/python3/dist-packages/eventlet/green/ssl.py", line 80, in __init__

  File "/usr/lib/python3/dist-packages/eventlet/green/ssl.py", line 426, in wrap_socket
    return GreenSSLSocket(sock, *a, _context=self, **kw)
  File "/usr/lib/python3/dist-packages/eventlet/green/ssl.py", line 80, in __init__
    *args, **kw
TypeError: wrap_socket() got an unexpected keyword argument '_context'

[Regression Potential]
Low; codepaths are all Python 3.7 specific due to internal changes in the SSL implementation.

[Original bug report]
In an SSL enabled OpenStack Stein deploy, deployed on Disco, the cinder-scheduler service is crashing with the below stacktrace:
