Cannot create network in horizon

Brief Description

Discovered by Bin, saw this error when trying to create a network in a private build. The neutron-api.log didn't have an error log.

Reproducible

[Ghada Khalil (gkhalil)]

This is minor. With the strategy to rebase to Stein, this will be taken care of automatically. No plan to address in the meantime.

[Ghada Khalil (gkhalil)]

Will re-test after the cut-over to containerized openstack.

[Ghada Khalil (gkhalil)]

This has been addressed in the StarlingX containerized environment.

[Ghada Khalil (gkhalil)]

The containerized environment has been merged to starlingx master on March 1/2019
