** Description changed:
Heat-dashboard fails to upload files.
[Impact]
Users cannot upload heat template files via the Openstack dashboard (see
failed ui screenshot)
"A template is used to automate the deployment of infrastructure,
services, and applications."
[Test Case]
1) Setup a basic openstack with heat and horizon
- generate a heat-template.yaml deployment (attached template.yaml)
2) After the regular cloud setup, try to upload the file via horizon
dashboard -> Project -> Stacks -> Launch stack (+)
- choose the template.yaml
3) Check openstack-dashboard/0 $/var/log/apache2/error.log and it should have
the error
```

try to upload the file via horizon dashboard -> Project -> Stacks -> Launch
stack (+)
- choose the template.yaml
- fill out admin password
- Launch
(the instance will be created)
you can tail the error.logs for apache2 inside of openstack-dashboard/o
under /var/log/apache2/error.log
I saw no errors when uploading the template file.
[Where problems could occur]
The information for the forms page could fail to load properly.
[Other Info]
Patch landed in Train and now going to Stein.
This is apython3 API change, Bionic/Queens are on python2, no fix needed in
those releases.
Openstack: Stein
OS: Ubuntu Bionic
