# This function is an hack because we are not enabling Puppet parser
# that would allow us to manipulate data iterations directly in manifests.
#
# Example:
# keystone_vips = ['192.168.0.1:5000', '192.168.0.2:5000']
# $keystone_bind_opts = ['transparent']
#
# Using this function:
# $keystone_vips_hash = list_to_hash($keystone_vips, $keystone_bind_opts)
#
# Would return:
# $keystone_vips_hash = {
# '192.168.0.1:5000' => ['transparent'],
# '192.168.0.2:5000' => ['transparent'],
# }
#
# Disclaimer: this function is an hack and will disappear once TripleO enable
# Puppet parser.
