Make edit monitor error type clearer

Before this change, edit monitor will send a EXCEEDED_RESOURCE_USAGE
error to clearcut, however, it does not tell whether it is due to memory
or CPU usage overload. This CL separate the errory type to
EXCEEDED_MEMORY_USAGE and EXCEEDED_CPU_USAGE to make it easier to debug
