Refactoring HoodieTableFileSystemView using FileGroups/FileSlices

Browse Source 
- Merged all filter* and get* methods
 - new constructor takes filestatus[]
 - All existing tests pass
 - FileGroup is all files that belong to a fileID within a partition
 - FileSlice is a generation of data and log files, starting at a base commit
