Sean Mooney 73fe84fa0e Support multiple config file with mod_wsgi
Unlike uwsgi, apache mod_wsgi does not support passing
commandline arguments to the python wsgi script it invokes.

As a result while you can pass --config-file when hosting the
api and metadata wsgi applications with uwsgi there is no
way to use multiple config files with mod_wsgi.

This change mirrors how this is supported in keystone today
by intoducing a new OS_NOVA_CONFIG_FILES env var to allow
operators to optional pass a ';' delimited list of config
files to load.

This change also add docs for this env var and the existing
undocumented OS_NOVA_CONFIG_DIR.

apache mod_wsgi does not support passing commandline arguments to the wsgi
application that it hosts. As a result when the nova api or metadata api
where run under mod_wsgi it was not posible to use multiple config files
or non-default file names i.e. nova-api.conf
This has been adressed by the intoduction of a new, optional, envionment
varible ``OS_NOVA_CONFIG_FILES``. ``OS_NOVA_CONFIG_FILES`` is a ``;``
seperated list fo file path relitive to ``OS_NOVA_CONFIG_DIR``.
When unset the default ``api-paste.ini`` and ``nova.conf`` will be used
form ``/etc/nova``. This is supported for the nova api and nova metadata
wsgi applications.
