Automatic Joiner failure recovery/retry

Registered by David Bennett on 2014-09-29

We need a facility to enable automatic retries in a joiner node after SST failure. There are multiple scenarios in which a node can fail to join a cluster, these include:

* Network connection failure
* underlying process failure (due to service or machine restrarts)
* Intermittent failure in the SST provider (xtrabackup, rsync, etc..)

When a joiner fails to apply the SST transfer. It should automatically retry to join the cluster. This may involve:

* Automatic clean or recovery of the joiner's data store.
* A 'join attempt' counter
* A user configurable join_attempts value to limit the retry attempts
* donor selection logic to avoid donor node specific SST creation/transfer issues.
