neutronclient with pre-determined auth token fails when doing Client.get_auth_info()

[Ihar Hrachyshka]

When token is provided on __init__, no authentication is actually done (fine) and client.httpclient.auth_[tenant|user]_id keys are not set (bad). This results in call to client.get_auth_info() to fail with KeyError (this was revealed when working with neutron-metadata-agent):

    Fixed get_auth_info() for pre-authenticated clients

    When a client is instantiated with pre-defined authorization token,
    no authentication is done, so no auth_[tenant|user]_id keys are set
    for HTTPClient. As a result, Client.get_auth_info() fails with KeyError.

    Fixed the issue by setting those keys on HTTPClient initialization.
