Additional path patterns for log readme files.

* modules/openstack_project/templates/logs-dev.vhost.erb
* modules/openstack_project/templates/logs.vhost.erb: With the
recent advent of an additional parent node in the job log path, the
ReadmeName was no longer being applied to new log directories. This
corrects it by adding duplicate Directory blocks for them with the
new pattern. Note that ReadmeName does not work inside regular
expression blocks like DirectoryMatch, but the old Directory blocks
can be removed when those logs expire in about 6 months time. Also
added patterns to provide readme files for equivalent periodic jobs.
