think SST/IST failed, at next restart will request a full SST
This patch fixes an unwanted behavior of a Galera cluster node when
Server startup fails because of an error in configuration file: after
the failure full SST is requested at the next Server startup even
though full SST is not needed (MDEV-31517).
If Server startup fails because of a configuration error, this patch
ensures that Galera state of the failing node remains unchanged. This
avoids full SST at the next Server restart.
This fix consists of three patches for the following components:
1) Server,
2) WSREP library,
3) Galera.
