d/t/pacemaker: corosync uses uname -n to define the default node name
requested to merge kanashiro/pacemaker:fix-autopkgtest-with-new-corosync-behavior into debian/master
Previously the default node name was hardcoded in the config file as node1.
This MP should be accepted in case this corosync MP is also accepted:
In Ubuntu, we changed the corosync behavior to use uname -n as the default node name instead of using the harcoded node1 name in the config file.
