Targeting stx.2019.03 - horizon issue with region config. Doesn't gate stx.2018.10 as it's not a common config

[Tyler Smith (tyler.smith)]

It may not be worth investigating this issue at the moment. The service catalog exception should go away when we finish the rebase to stein, as we are getting rid of the auto-refresh feature (which i think is the cause), and the server group panel reporting the second exception is being replaced by the upstream angular panel (of which there is a different error being noticed which is having it's own launchpad created)

Based on Tyler's comment, I will close this bug as invalid for the recent changes.
