Fix proposed to branch: master

glance_store uses bare ConfigParser for swift configuration:
https://github.com/openstack/glance_store/blob/stable/stein/glance_store/_drivers/swift/utils.py
(affects both ConfigParser and SafeConfigParser in PY3)

that ceased to strip quotes in PY3. That leads to invalid auth parameters and failure to authenticate: 'project_domain_id': '""', 'user_domain_id': '""'

    Don't use quotes in glance swift configuration

    glance_store uses bare ConfigParser for swift configuration, that
    ceased to strip quotes in PY3. That leads to invalid auth parameters
    (e.g. 'project_domain_id': '""') and failure to authenticate.

    Current CI process does not hit this issue because Swift backend
    is not used.
