@sreejasahithi Thanks for working on this. Please find the comments inline.
Also can you create a utility class and put common methods there instead adding everything in the same class.

@sreejasahithi overall LGTM, some minor nits.

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 version 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 version 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 file to the staging location.
We should also update copy plan with staging -> final path mappings for each metadata version file rewritten.
