Description of problem:

dlm 4.1.0 requires the quorum_model_initialize function in corosync, which was introduced in corosync v3.1.0. dlm_controld fails to start if an older version of corosync is installed.

Aug 9 22:30:59 node1 pacemaker-execd[91995]: notice: dlm_start_0[92121] error output [ dlm_controld: symbol lookup error: dlm_controld: undefined symbol: quorum_model_initialize ]
Aug 9 22:30:59 node1 pacemaker-controld[91998]: notice: Result of start operation for dlm on node1: not running

dlm 4.1.0 currently requires only corosync >= 1.99.9.

[root@fastvm-rhel-8-0-23 pacemaker]# rpm -q --requires dlm | grep corosync
corosync >= 1.99.9

Version-Release number of selected component (if applicable):

How reproducible:

Always

Steps to Reproduce:
1. Install dlm-4.1.0-1.el8 and a corosync version less than 3.1.0.
2. Try to start dlm_controld (for example, via the ocf:pacemaker:controld resource agent).

Actual results:

dlm_controld: symbol lookup error: dlm_controld: undefined symbol: quorum_model_initialize

Expected results:

dlm_controld starts without issue.
