SERVER-5092 basic.h should not be present in a header context
SERVER-14415 extended LogComponent and LogComponentSettings to support hierarchy of component log levels
SERVER-14415 added yaml config options to set log component hierarchy verbosity levels
SERVER-14416 added server parameter logComponentVerbosity.
             This supports the use of BSON objects in querying/updating the log component hierarchy.
SERVER-5092 removed logLevel_* server parameters. these have been replaced by a single server parameter logComponentVerbosity
