Operators may need to clear pending files from the datalake coordinator when Iceberg catalog state becomes inconsistent (e.g. after manual catalog modifications) which can result in stuck coordinator. The new CoordinatorResetState RPC is exposed via the admin API with SUPERUSER authorization and plumbed through the coordinator frontend, RPC service, and state machine. (cherry picked from commit c6f5621)
In some cases we want to manually choose from where translation should resume after a coordinator reset. Add per-partition last_committed overrides and a reset_all_partitions flag. By default reset_all_partitions is false and the request is a no-op unless partition_overrides are provided — only the listed partitions have their pending entries cleared and last_committed set. Setting reset_all_partitions to true clears all partitions first, then applies any overrides. This default-safe design minimizes surprise and makes it harder to accidentally wipe state. (cherry picked from commit f44ca9d)
