This PR removes a potential cause of data loss when migrating system indices. It does this by changing the way we set a "write-block" on the system index to migrate - now using a dedicated transport request rather than a settings update. Furthermore, we no longer delete the write-block prior to deleting the index, as this was another source of potential data loss. Additionally, we now remove the block if the migration fails.
