Description
Closes #14822
Allow Iceberg writes to use either append or fastAppend. Users in certain use cases may want to do compaction of Manifests async from writes. We should allow configuring fastAppend for that situation on a session level basis.
Additional context and related issues
New IcebergSessionProperty iceberg.merge_manifests_on_write . Default value - "true".
SET SESSION iceberg.merge_manifests_on_write = false to force fastAppend()
SET SESSION iceberg.merge_manifests_on_write = true to force append()
