Create PEL if unable to get the OCC PDRs

The OCC PDRs are required so occ-control will know when the OCCs are
available and ready to communicate. If the PDRs never become available
there is currently no indication other than the OCC sensors not being
available.
This code change will create a PEL when the PDRs have not been found
after 5 minutes. The service will continue looking for the PDRs after
logging the PEL.
