> Current log-aggregation implementation supports logaggregation to default 
> filecontext only. This patch is to support logaggregation to any of the 
> supported filesystems within hadoop eco-system (hdfs, s3, swiftfs etc). So 
> for example a customer could use hdfs as default filesystem but use s3 or 
> swiftfs for logaggregation. Current implementation makes mixed usages of 
> FileContext+AbstractFileSystem apis as well as FileSystem apis which is 
> confusing.
> This patch does two things:
> # moves logaggregation implementation to use only FileContext apis
> # adds support for doing log aggregation on non-default filesystem as well.
> # changes TestLogAggregationService to use local filesystem itself instead of 
> mocking the behavior
