Check that cluster weight have proper values in galera_pc_weight
test. Removed sleeps from tests and added condition waits for
expected cluster sizes. Replaced galera suspend/resume with
gmcast.isolate in order to avoid breaking client connections
to server which is isolated from the cluster and to avoid
the need to reset wsrep_cluster_address.
Re-recorded galera_defaults.
Test galera_3nodes.galera_pc_weight started to fail because it
expects to use wait_until_connected_again while remaining in
non-primary view. Hopefully this is the only test which makes
this assumption, and fortunately those wait_until_connected_again
seem unnecessary, so this patch removes them.
Problem:- Gtid are not transferred in Galera Cluster.
Solution:- We need to transfer gtid in the case on either when cluster is
slave/master in async replication. In normal Gtid replication gtid are generated on
recieving node itself and it is always on sync with other nodes. Because galera keeps
node in sync , So all nodes get same no of event groups. So the issue arises when
say galera is slave in async replication.
A
| (Async replication)
D <-> E <-> F {Galera replication}
So what should happen is that all node should apply the master gtid but this does
node happen, becuase node E, F does not recieve gtid from D in write set , So what E(or F)
does is that it applies wsrep_gtid_domain_id, D server-id , E gtid next seq no. This
generated gtid does not always work when say A has different domain id.
So In this commit, on galera node when we see that this event is recieved from master
we simply write Gtid_Log_Event in write_set and send it to other nodes.
* a dedicated test for wsrep_retry_autocommit
* some galera_toi_* tests were only passing because wsrep_retry_autocommit
was in effect. The tests were changed to do not use autocommit
* higher timeout values in galera_2nodes.cnf , galera_3nodes.cnf

Problem:- While running individual tests of Galera_3nodes ,
We get warnings like '[Warning] WSREP: Could not open state file
for reading: '. And because of this individual tests fails.
Solution:- We change suite.pm of Galera_3nodes to supress these warnings.
