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

[Ghada Khalil (gkhalil)]

There are significant changes required to support Distributed Cloud in stx due to the containerized environment. Based on discussion with the Distributed Cloud PL, Dariush Eslimi, we agreed to close old Distributed Cloud bugs as Won't Fix. A full test cycle will be needed to verify the new implementation and new bugs can be opened for the issues reported then.

closing per wont fix decision above
