os_transport_url fails when an array of size 1 is passed in as the hosts param

[Alex Schultz]

When using os_transport_url and passing in ['localhost'] to the hosts parameter, puppet fails with a map error.

Error: Evaluation Error: Error while evaluating a Function Call, undefined method `map' for \"overcloud-controller-0.internalapi.localdomain\":String at /etc/puppet/modules/tripleo/manifests/profile/base/heat.pp:82:28 on node overcloud-controller-0.localdomain\u001b[0m\n

This is due to os_transport_url calling normalize_ip_for_uri which will convert an array of size 1 to a string.
