Correct used configuration and force server restarts before test
case. Add wait condition instead of sleep to verify that
all expected nodes are back to cluster.

This commit fixes GTID inconsistency which was injected by mariabackup SST.
Donor node now writes new info file: donor_galera_info, which is streamed
along the mariabackup donation to the joiner node. The donor_galera_info
file contains both GTID and gtid domain_id, and joiner will use these to
initialize the GTID state.
Commit has new mtr test case: galera_3nodes.galera_gtid_consistency, which
exercises potentially harmful mariabackup SST scenarios. The test has also
scenario with IST joining.

This commit fixes a crash reported as MDEV-28377 and a number
of other crashes in automated tests with mtr that are related
to broken .cnf files in galera and galera_3nodes suites, which
happened when automatically migrating MDEV-26171 from 10.3 to
subsequent higher versions.
This commit fixes a crash reported as MDEV-28377 and a number
of other crashes in automated tests with mtr that are related
to broken .cnf files in galera and galera_3nodes suites, which
happened when automatically migrating MDEV-26171 from 10.3 to
subsequent higher versions.
This commit adds a mtr test for reproducing a test scenario where despite of
innodb_disallow_writes blocking, writes to file system can still happen.
The test launches a garbd node, which triggers one of the cluster node to switch to
SST donor state. In this state, all disk activity should be halted, and e.g.
innodb_disallow_writes has been set. The test records md5sum aggregate over mariadb
data directory when the node enters the donor state, and records another md5sum
when the node leaves the donor state. If there is no IO activity in data directory, these
hashes should be equal.
For this test, the Donor state processing, has beeen instrumented so that, SST donor thread can be
stopped when entering the donor state. The test uses this new dbug sync point,
to control when to record the md5sums.
New SST script was added: wsrep_sst_backup, and garbd uses backup method to lauch the donor
node to call this script, and to enter in donor state.
The backup script could be later extended as general purpose backup method for the cluster.
This commit fixes also one race condition happening in wsrep_sst_rsync, like this:
* wsrep_rsync_sst script requests for flush tables,
and then waits in a loop until mariadbd has created file tables_flushed,
as confirmation that FLUSH TABLES has completed
* mariadbd's SST donor thread, wakes for the flush table request and then performs FTWRL,
and after this it creates the tables_flushed file
* note that SST script will now continue to startup rsync sending
* mariadbd's SST donor thread now calls for sst_disallow_writes(),
so that innodb would setup disk IO blockage, however rsyncing may already be ongoing at this point
This race condition is fixed in this commit, by performing all disk IO blocking before
creating the tables_flushed file.
