Improvements

PXC-851: Added version compatibility check during SST with XtraBackup:
- If donor is 5.6 and joiner is 5.7: A warning is printed to perform mysql_upgrade.
- If donor is 5.7 and joiner is 5.6: An error is printed and SST is rejected.

Fixed Bugs

PXC-825: Fixed script for SST with XtraBackup (wsrep_sst_xtrabackup-v2) to include the --defaults-group-suffix when logging to syslog. For more information, see #1559498.

PXC-827: Fixed handling of different binlog names between donor and joiner nodes when GTID is enabled. For more information, see #1690398.

PXC-830: Rejected the RESET MASTER operation when wsrep provider is enabled and gtid_mode is set to ON. For more information, see #1249284.

PXC-833: Fixed connection failure handling during SST by making the donor retry connection to joiner every second for a maximum of 30 retries. For more information, see #1696273.

PXC-841: Added check to avoid replication of DDL if sql_log_bin is disabled. For more information, see #1706820.

PXC-853: Fixed cluster recovery by enabling wsrep_ready whenever nodes become PRIMARY.

PXC-862: Fixed script for SST with XtraBackup (wsrep_sst_xtrabackup-v2) to use the ssl-dhparams value from the configuration file.
