Implement the rdc_lib API to support the job stats

Add the function to start and stop the job recording.
Add the function to get the job stats for each GPU and summary of multiple GPUs
Add the function to remove the jobs.

Add a class RdcLogger which can control the log level using the environment variable RDC_LOG.
This is similar to GRPC_VERBOSITY gRPC. When the customer has the issues, he can enable the verbose
log to help us to troubleshoot the issues.

Add the -u support in the rdci group, fieldgroup and dmon for connecting to rdcd without authentication.
