Add example Apache config files

This patch is needed in 1.9 as a dependency for adding swift/apache
to devstack.
zhang-hare is working in parallel on a devstack patch that depend
on this patch.

As part of this patch we add examples dir.
In this dir we add template config files that can be used either by
a script (as will be done by devstack) or serve a an example to the
admin.

Apache2 vhost files were added under examples/apache2
Wsgi files were added under examples/wsgi

Fixes: Bug #1191388
