Copy all apache logs into output

In I4b664a1d6c9bbb1ff999158f3a8c8ab3bd8d891b keystone switched to
running as a wsgi app under apache.  Swift and ceilometer etc can also
run under apache and might change one-day.

I strongly suspect failures in
I9f8b703aa7e4f064656141a548bff014be500daf is related to permissions
error in keystone but I can't see any relevant logs.

Rather than try and do things piecemeal which might miss things again
in the future, this copies everything in /var/log/[apache2|httpd] into
the log output.
