Most OpenStack API communication uses the cafile option in the
service_credentials config. For swift the client is created differently,
and does not get this option. When TLS is used, we may get an error like
the following:
exceptions.SSLError: HTTPSConnectionPool(host='1.2.3.4', port=443): Max
retries exceeded with url: /swift/v1/AUTH_XXXX (Caused by
SSLError(SSLError("bad handshake: Error([('SSL routines',
'tls_process_server_certificate', 'certificate verify failed')],)",),))
This change fixes the issue by creating an HTTP connection for the Swift
client that uses the configured CA file.
