[ClusterLabs] Adding HAProxy as a Resource

[Tomas Jelinek]

Hi,

Do you have a systemd unit file for haproxy installed?
Does 'crm_resource --list-standards' print 'systemd'?
Does 'crm_resource --list-agents systemd' print 'haproxy'?
Note that when you use full agent name (that is including : ) it is case 
sensitive in pcs.

Regards,
Tomas
