mb/ocp/deltalake: Set FSP log level and add default values if VPD variables are not found
1. Read VPD variable 'fsp_log_level' to decide FSP log level. 2. Define the default values when the VPD variables cannot be found, put all the values to vpd.h for better documentation and maintenance. Tested=On OCP DeltaLake, the fsp_log_level can be changed from the VPD variable.
