Waiting for this to make it in: ManageIQ/manageiq-api#167

This pr does NOT fix: https://bugzilla.redhat.com/show_bug.cgi?id=1505546 a separate pr will be required for this

@AllenBW looks like ManageIQ/manageiq-api#167 is merged, I restarted the build on this (Node 6 failed...thinking it is just Travis being Travis). Can this be merged?

[AllenBW]

This is good to go! @chriskacerguis

@AllenBW Please create a separate PR for Fine branch - none of the files are clean cherry-pick...

[AllenBW]

@simaishi ok don't wantcha to think i forgot about this, so looks like this work isn't enough to get the fix we want, what WILL BE (should be) the end of all this is #1280 so from that, we'll make a fine and euwe branch so it all gets in alrite alrite

[simaishi]

@AllenBW #1280 was backported to Fine via #1282. Is this PR still needed for Fine branch?

[AllenBW]

@simaishi Nope!! This pr ended up not being a fix, no need to backport it.
