    Allow Swift daemons and servers to optionally accept a directory as the
    configuration parameter. Directory based configuration leverages
    ConfigParser's native multi-file support. Files ending in '.conf' in the
    given directory are parsed in lexicographical order. Filenames starting with
    '.' are ignored. A mixture of file and directory configuration paths is not
    supported - if the configuration path is a file behavior is unchanged.

     * update swift-init to search for conf.d paths when building servers
        (e.g. /etc/swift/proxy-server.conf.d/)
     * new script swift-config can be used to inspect the cumulative configuration
     * pull a little bit of code out of run_wsgi and test separately
     * fix example config bug for the proxy servers client_disconnect option
     * added section on directory based configuration to deployment guide
