Bug description:
  [ Impact ]
  Octavia fails to provision Amphora for load balancers.

  [ Test Plan ]
  Install Octavia as part of a Charmed OpenStack deployment for Caracal.
  Create a loadbalancer - creation will fail with stack trace from original bug report.

  [ Where problems could occur ]
  The fix for this is to ensure that data files in the Python source tree are included in the package installation; this is done by providing a MANIFEST to ensure that this happens; side effects are unlikely.

  [Original Bug Report]
  [Impact]

  Octavia fails to provision the amphora, the stacktrace logged is:
