Method initialize_caliper

src/utils/profiling.cpp:222–247

The rules for caliper: - If CALI_CONFIG is set and nonempty, initialize caliper but ignore "--caliper_config". - if "--caliper", setup with "--caliper_config". - Otherwise, do nothing.

//   - if "--caliper", setup with "--caliper_config".
//   - Otherwise, do nothing.
