rlog tracing granularity

Description

Currently we only have two levels of rlog tracing -- summarized and detailed ('timing' and 'log'). In the detailed profiling, for channels like nemesis which do polling, there is some state information stored for each poll. Similarly, for atomic operations every operation is logged. This adds too much overhead and makes the logs very large as well. We should consider adding at least one more level for such logging which will allow for an intermediate granularity, i.e., log everything except fine grained operations such as polls and atomics.
