Michele Baldessari ee7be9b7ad Do not fail fencing configuration when instanceha is disabled
Right now we fail like this if fencing is enabled but instanceha is not:
"Error: Evaluation Error: Error while evaluating a Function Call, Could not find data item compute_instanceha_short_node_names in any Hiera
data file and no default supplied at /etc/puppet/modules/tripleo/manifests/fencing.pp:61:13 on node controller-0.localdomain"

# == Class: tripleo::fencing
#
# Configure Pacemaker fencing devices for TripleO.
#
# === Parameters:
#
# [*config*]
# JSON config of fencing devices, using the following structure:
# {
# "devices": [
# {
# "agent": "AGENT_NAME",
# "host_mac": "HOST_MAC_ADDRESS",
# "params": {"PARAM_NAME": "PARAM_VALUE"}
# }
# ]
# }
# For instance:
# {
# "devices": [
# {
# "agent": "fence_xvm",
# "host_mac": "52:54:00:aa:bb:cc",
# "params": {
# "multicast_address": "225.0.0.12",
# "port": "baremetal_0",
# "manage_fw": true,
# "manage_key_file": true,
# "key_file": "/etc/fence_xvm.key",
# "key_file_password": "abcdef"
# }
# }
# ]
# }
# Defaults to {}
#
# [*tries*]
# Number of attempts when creating fence devices and constraints.
# Defaults to 10
#
# [*try_sleep*]
# Delay (in seconds) between attempts when creating fence devices
# and constraints.
# Defaults to 3
#
# [*enable_instanceha*]
# (Optional) Boolean driving the Instance HA controlplane configuration
# Defaults to false
