Pacemaker resources are stopped when corosync cluster lacks quorum, astute does not check amount of controllers

[Igor Zinovik]

After commit 1a0e360cd14bf3511bc8e390b54ee2530399d12c was merged in fuel-library/
repository astute changes pacemakers quorum policy to 'stop'. This means that when pacemaker
cluster does not have quorum (1 or 2 controllers) it will stop all pacemaker resources.

Expected result:
Cluster without quorum has no-quorum-policy=ignore

Actual result:
All pacemaker resources are stopped.

Workaround:
$ pcs property set no-quorum-policy=ignore

Impact:
deployment fails becase services and IP addresses are stopped/disabled.
