Backported the fix done by Pekka Lampio for mariaDB 11.4 in PR https://github.com/mariadb-corporation/codership-mariadb-server/pull/543 The PR has a fix for wsrep_sst_rsync script and new mtr test: galera_3nodes.galera_mdev_36677" to check that the rsync SST method of Galera works correctly also when the joiner node store InnoDB log files in a dedicated directory separate from the data dictionary Note: merging this PR to 11.4 may not be fully functional as there are other changes in the rsync SST script. Take a look at the original 11.4 PR when merging.

# This test checks the rsync SST works also when InnoDB log files
|
|
# reside in a dedicated directory other than the data directory.
|
|
|
|
# The test comprises of two parts: in Part A the SST donor has InnoDB
|
|
# log files outside the data dictionary and in Part B the SST joiner
|
|
# has log files outside the data dictionary.
