FAR installs agents that are not meant for our goal of powering off and on a host/node.
Since FAR won't rely on a Pacemaker (at least not recommended), it was designed to use power-based agents and the agents shouldn't use Telnet/SSH.

Comments on the possible agents to remove

• fence-kdump fence-sbd = special in their own way and not so recommended for our use case
• fence-scsi, fence-mpath, fence-cisco-mds = Resource based agents that usually have been using with pacemaker
• fence_heuristics_ping = Is no real fence-agent on its own but design to work together with other fence-agents in a topology.
• fence_compute = is for OSP. Can be used in the case of OpenShift on Openstack
