Support extra metrics in the RDC

Remove the * in the rdci stats
When a group is created, the GPUs can be added in the same command.
Add the support to the memory temperature.
Add the support to the memory clock.
Add the support to report the ECC errors.
Add the support to report the PCIe bandwidth throughput.

Since the RX/TX throughput may take 1 second to retreive, an async fetch is implemented
in the RdcMetricFetcherImpl.
