log_level set in the conf file has no effect on non-sandesh logs

[Sundaresan Rajangam]

Presently, only the sandesh systemlog messages honor the log_level set in the conf file. As a result, all the non-sandesh log messages are written in the log file irrespective of the log level.
The value of log_level (sandesh level) in the conf file (or the default value) should be converted to appropriate log4cplus::LogLevel and set in the log4cplus logger.
