Attempting to run openstack commands from the director node against the "overcloud" fail to reach overcloud service URL

Issue

• When we ssh to the stack user on our undercloud node and do a source ./overcloudrc and attempt to run commands, such as openstack compute service list, the command hangs for a period of time and then fails:

[stack@director ~]$ source ./overcloudrc 
(overcloud) [stack@director ~]$ openstack compute service list
Failed to discover available identity versions when contacting https://overcloud.localdomain:13000//v3. Attempting to parse version from URL.
Could not determine a suitable URL for the plugin

• If we ssh as heat-admin to one of the controller nodes, source the overcloudrc, and run the same command, it succeeds:

[stack@director ~]$ ssh heat-admin@overcloud-controller-0

• From what we can gather, the openstack overcloud commands should be working correctly from the undercloud node.
