What changes were proposed in this pull request?
This change implements the logic to rewrite table metadata version files across the metadata history, enabling path migration from a source prefix to a target prefix.
Traversal should start from the provided endMetadata (current or specified version) and iterate backwards through previous metadata files until reached the startVersion provided if any(if not then till beginning). We also need to collect all the snapshots from each traversed historical metadata version.
For each metadata file we can take help of iceberg's RewriteTablePathUtil to rewrite absolute file paths in it from sourcePrefix -> targetPrefix and then we have to add the rewritten metadata file to the staging location.
We should also update copy plan with staging -> final path mappings for each version file rewritten.
