refactor(log): adjust log level and macro names

[acelyc111]

#1199

For historical reasons, the log levels of Pegasus is a bit of confused and not consistent with other well known and wildly used logging systems. This patch aim to resolve this issuse, includes the following changes:

• Re-order log levels to: DEBUG,INFO,WARNING,ERROR,FATAL, see src/runtime/task/task_spec.h, src/utils/api_utilities.h,
• Change the log relationship between libevent and Pegasus, see src/reporter/pegasus_counter_reporter.cpp
• Change the log relationship between sasl and Pegasus, see src/runtime/security/sasl_init.cpp
• Simplify LOG_LEVEL_INFORMATION to LOG_LEVEL_INFO
• Change logging macros:
  • dinfo -> LOG_DEBUG
  • ddebug -> LOG_INFO
  • dwarn -> LOG_WARNING
  • derror -> LOG_ERROR
  • dfatal -> LOG_FATAL
• Update related tests
• Update related config files
• Update all places using the macros above

Of course, this patch will take effect on thousands of source files, I used IDE to replace the macros, and I've checked these files one by one manually. Reviewers could check the following files to save time:

1. src/reporter/pegasus_counter_reporter.cpp
2. src/runtime/security/sasl_init.cpp
3. src/runtime/task/task_spec.h
4. src/utils/api_utilities.h
5. src/utils/fmt_logging.h
6. src/utils/test/logging.cpp

TODO: log levels using fmt (e.g. dinfo_f, dwarn_f) is left as before and will be refactored in the next patch.

Compatibility

Log levels of DEBUG and INFO are exchanged, should be mentioned in release note.
