Cannot use audit middleware with Swift because cfg.CONF.project does not exist

[Guang Yee]

Audit assumes cfg.CONF.project is set.

This is only true for services using oslo.config. But since Swift have no dependency on oslo.config, this option may not get registered or even exist. You may see an traceback in Swift which ends with something like this

"oslo_config.cfg.NoSuchOptError: no such option in group DEFAULT: project"

We need to follow the same pattern as auth_token to determine the project. See

    Determine project name from oslo_config or local config

    For services such as Swift, which may not be utilizing oslo_config, we need
    to be able to determine the project name from local config. If project name
    is specified in both local config and oslo_config, the one in local config will
    be used instead.

    In case project is undetermined (i.e. not set), we use taxonomy.UNKNOWN
    as an indicator so operators can take corrective actions.
