Public bug reported:

Netscaler client code has an incorrect exception handling order,
resulting in the SSLError case never being invoked:

neutron.services.loadbalancer.drivers.netscaler.ncc_client.NSClient._execute_request
has a list of exception handlers to log various types of errors with
more specific error messages.  Unfortunately, it catches
requests.exceptions.ConnectionError before requests.exceptions.SSLError,
but ConnectionError is a superclass of SSLError so the latter is never
invoked.
