Ayumu Ueha b689b6320c Fix default value for wsrep_sync_wait option
The default value for wsrep_sync_wait option should be `None`.
However, since 0 is set incorrectly, an unintended process is executed.

This patch fixes default value for wsrep_sync_wait option to `None`
instead of `0`.

The newly added mysql_wsrep_sync_wait parameter now defaults to non-present
in the enginefacade's default configuration options, so that it is not
configured in a MySQL / MariaDB database by default, unless passed in the
options explicitly. Previously, the default value was "0", meaning the
wsrep_sync_wait parameter would be set unconditionally on new connections,
which would fail for MySQL backends that don't provide for this setting.
