HIVE-25406: Fetch writeId from insert-only transactional tables

[kasakrisz]

What changes were proposed in this pull request?

• introduce the table property insertonly.fetch.bucketid. When this is set to true a tablescan on the table will provide bucketId and writeId for each record
• parse bucket and writeId from the directory names contain the bucket files of the tables. This is called in the Record readers.
• Add the BucketIdentifier class to hold the parsed bucket and writeId.
• The new insertonly.fetch.bucketid property is handled by AcidOperationalProperties and the existing acid.fetch.deleted.rows is also moved to here.
• For compacted files the bucket and writeId values are null

Why are the changes needed?

Enable incremental rewrite of materialized views which has insert only source tables.

Does this PR introduce any user-facing change?
