This change adds a retry to the mysql_upgrade command when performing an upgrade. This is required in circumstances when the wsrep service is not ready for application use. This is a common issue when restarting the mysql service after package installation. Example Error: Got error: 1047: WSREP has not yet prepared node for application use when selecting the database Change-Id: Icd859531b6a6f1e04ecd1214eb7c401fa0fe8048 Signed-off-by: Kevin Carter <kevin.carter@rackspace.com>
