Handle reported unrecoverable errors from donors/recipients in the coordinator

    XMLWordPrintable

    Description

      The coordinator observer will see the write to config.reshardingOperations and see that the write changes a shard to error. The coordinator will then update itself to the error state. Then it will refresh all shards. After all shards have returned that they've updated to the error state, the coordinator should indefinitely attempt to remove all resharding metadata that currently exists.

      Also take care of all TODOS linked in SERVER-53006 in this ticket, then close both in one commit. These TODOS are currently tied to the duplicated ticket SERVER-51800.
