Throttle PLDM traces after 5 minutes while waiting for PDRs

Existing code waits up to 40 minutes for the OCC active sensors PDRs to
be available. If not available, a BD8D2685 PEL will get logged and
occ-control will continue to wait for the PDRs.

This change will throttle the occ-control PLDM traces after 5 minutes,
while continuing to wait for the PDRs. A PEL will still get generated if
the timeout expires.

Tested on Rainier

OpenPOWER OCC Control Service

This service will handle communications to the On-Chip Controller (OCC) on Power processors. The OCC provides processor and memory temperatures, power readings, power cap support, system power mode support, and idle power saver support. OCC Control will be interfacing with the OCC to collect the temperatures and power readings, updating the system power mode, setting power caps, and idle power save parameters.

The service is started automatically when the BMC is started.

Build Project

This project can be built with meson. The typical meson workflow is: meson builddir && ninja -C builddir.

Server

The server will start automatically after BMC is powered on.

Server status: systemctl status org.open_power.OCC.Control.service

To restart the service: systemctl restart org.open_power.OCC.Control.service

Configuration

Service files are located in service_files subdirectory.
