High: ais: Bug lf#2359 - Default expected votes to 2 inside Corosync/OpenAIS plugin
If, on a new cluster, 3 or more nodes are seen before the crmd sets expected votes to
it's default (2), then the update will be rejected and the cluster will continue using
1024 everywhere.
Although it is possible to change this using 'crm configure property expected-votes=$N',
anyone hitting the race condition is going to be mighty confused.
So we adopt the same default as the crmd.
