  python3-heat-dashboard launch stack fails

Status in Ubuntu Cloud Archive:
  Invalid
Status in Ubuntu Cloud Archive stein series:
  Fix Released
Status in heat-dashboard package in Ubuntu:
  Invalid

Bug description:
  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
  ```

  # use sshuttle for reverse proxy to your openstack instance
  sshuttle -r ubuntu at X.X.X.X X.X.0.0/24

  testing with fix
  # add my ppa or use debdiff inside of openstack-dashboard/0

  # ssh to openstack dashboard container
  # use new heat-dashboard deb
  # restart apache2
  # try and upload template.yaml again
  juju ssh openstack-dashboard/0

  #remove existing python3-heat-dashboard version
  sudo apt-get remove python3-heat-dashboard

  sudo add-apt-repository ppa:hypothetical-lemon/heat-dashboard
  apt-get update

  # make sure the version is newest (heat-dashboard_1.5.0-0ubuntu3~cloud1)
  sudo apt-cache policy python3-heat-dashboard

  # restart apache2
  systemctl restart apache2

  # go to error log
  cd /var/log/apache2
  tail -f error.log

  # in a new terminal

  on the openstack cli

  # open a private session with brower
  copy and paste ip from your floating ip list command into the browser url

  #Note: an image must be available for use before attempting a file upload
  I did this through the UI, but cli works too

  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

  # how to find new Openstack dashboard credentials

  VERIFICATION DONE
  I was able to successfully launch a new stack from the template gui. 
  # enabled proposed
  Enabled the bionic-proposed repository in the openstack-dashboard container.
  #removed old version
  sudo apt-get remove python3-heat-dashboard
  # dpkg -l python3-heat-dashboard | cat
  Ensured that the version number is latest (python3-heat-dashboard 1.5.0-0ubuntu3~cloud1)
  # restart apache
  sudo systemctl restart apache2
  # created an image from iso via openstack gui
  # created a new network and subnet via openstack gui
  # launched Orchestration -> Stacks -> +Launch Stack 
  # seleted template.yaml modified with corrected subnet 
  # was able to see stack created and no errors in log file 
  # /var/log/apache2/error.log
