MAPREDUCE-7315. LocatedFileStatusFetcher to collect/publish IOStatistics. (#2579)
Part of the HADOOP-16830 IOStatistics API feature.

If the source FileSystem's listing RemoteIterators
implement IOStatisticsSource, these are collected and served through
the IOStatisticsSource API. If they are not: getIOStatistics() returns
null. 

Only the listing statistics are collected; FileSystem.globStatus() doesn't
provide any, so IO use there is not included in the aggregate results.
