# Function: load_helix_topology
#
# Input:
# $1 - Helix Topology file path
# $2 - Helix Topology file required format version.
#
# The following global arrays are updated:
#
# * InstanceUserPorts associative array
# * InstanceMasterHost associative array
# * InstanceServerPort associative array
# * InstanceBrokerPort associative array
# * InstanceManaged associative array
# * InstanceDesc associative array
#
# Instance definition:
# Form: INSTANCE|Name|UserPorts|MasterHost|ServerPort|BrokerPort|Managed|Desc
# Example:
# INSTANCE|fgs|perforce:1666|helix-01|1999|1666|Friendly Greeting Systems
#
# Return:
# 0 - Instances loaded, syntax verified.
# 1 - Errors detected.
