> The OpenStack provider (and by extension, the Rackspace provider) does not check to see
if the authentication token has expired before attempting to use it.
> In {{libcloud/common/openstack.py}} at {{OpenStackBaseConnection._populate_hosts_and_request_paths}},
the library checks that a token exists, and creates it if it does not.
> The issue is that it does not check if the token has expired, despite having this information
in {{self.auth_token_expires}}.
> So a long-running Python process will eventually fail because the token will expire,
and the API will return {{HTTP 401 Unauthorized}}.
> I've written a hacky workaround to this, by copying {{OpenStackAuthConnection._is_token_valid}}
into {{OpenStackBaseConnection}}, then replacing the {{_populate_hosts_and_requests_paths}}
auth token check with a call to {{_is_token_valid}}.
> This is shown in this commit: https://github.com/Caramel/libcloud/commit/317a039
> There's probably a better way to implement it without duplicating this function, but
I don't know enough of the codebase to make this change.  I'm also unsure if other drivers
also have this problem that are not based on OpenStack.
