jjb: use default logrotate setting in all projects

Many projects have own logrotate definitions copied from the template.
This patch make sure all projects to use the default logrotate setting,
so that the infra admin can configure the values easily.

This patch also fixes the logrotate rule for artifacts to keep them
in the same duration as console logs exist. Note, this won't effect
the hold time of artifacts in artifact.opnfv.org .
