tools/config/generate_sample.sh has no effect on OS X

We don't really support using this tool on OS X. It should be possible to make it work, but as that's not a platform we use for OpenStack development it hasn't been a priority.

Weird,

seems to work for me

The version of the config generator in oslo.config should work as long as the modules can be imported, so I'm going to close this wontfix.

Adding keystone here then, so we can switch from the shell version (which does not work on OS X) to the python version (which does work on OS X).

    switch from sample_config.sh to oslo-config-generator

    This switches keystone to use oslo-config-generator, where the contents
    of our sample configuration file are configured using a configuration
    file in config-generators/, because the only way to have tox create
    files is to have configuration files for your configuration files
    (seriously, it chokes when redirects are included in the command for a
    test environment).

    This also takes advantage of oslo-config-generator's ability to set the
    line wrap width, which is done at 79 chars here to match the rest of our
    code.

    Also update the actual sample file under etc/
