Add RefreshIncrementalAction class to support index creation on newly appended data

[apoorvedave1]

Describe the issue

Implement incremental indexing support for append-only data. Implementation outline:

• identify newly added data files
• create new index version on these files
• update metadata to reflect the latest snapshot of index to include old files and new files

New Api: refresh(mode = quick)

I think file size and modification time for each file are also required to ensure that the files are not modified. Currently we identify this with the signature value, but supporting append data (+ hybrid scan) needs to check if the existing index can cover the subset of dataset or not.
