Reducing severity to high as we need to wait if/how underlying RHEL issue is handled. But at the moment we cannot do anything about it

So according to platform bug BZ1481280, they will not re-enable no longer secure cipher 3des-cbc, so the only way how to use the cipher is to specify it in additional paramater for fence_drac5 agent using Options field in webadmin: ssh_options="-oCiphers=+3des-cbc" Unfortunately we are not able to enter such value into Options field as it somehow breaks our current validation.
Using ovirt-engine-4.1.8.1-0.1.el7.noarch and adding ssh_options="-oCiphers=+3des-cbc" still gives me unable to login error
Moving back to modified, because we have already provided the infra to be able to set key=key=value into Options field of Fence Agent. If platform doesn't change the defaults, then users will need to set login_timeout=30 along with ssh_options="-oCiphers=+3des-cbc" into Options field. Otherwise specifying ssh_options is enough
Verified on ovirt-engine-4.1.9-0.2.el7.noarch Using these values in options field: ssh_options="-oCiphers=+3des-cbc,login_timeout=30
