What would you like to be added:
In this PR: #818, we have added support for handling AWS S3's object lock mechanism in the backup-restore, ensuring that snapshots are immutable. However, if users want backup-restore to skip or ignore certain snapshots, we need to implement a similar approach to what is currently available for other providers like GCS and ABS. These providers allow users to tag snapshots (with certain key), which they wish to be ignored by backup-restore . For more information, please refer to the documentation

Why is this needed:
When snapshots were mutable(if object lock isn't enabled), operators could simply delete any snapshots present in the object store, and subsequent restorations would not include them. However, once immutability is enabled, it is no longer possible to delete these snapshots. Hence, there should be a mechanism available for backup-restore to ignore any of snapshots during restoration.
