dashboard does not have buttons on consistency groups tab

[Ashley Lai]

On Xenial-Queens, under Volumes->Consistency Groups tab does not have any button to create/manage consistency group.

I was able to create a consistency group using the cinder command but it does not show it on the dashboard.

Confirmed in bionic-queens

No create button displayed or in page source.

TRIAGE:

Determine if this is a configuration bug or a horizon bug.

Subscribing field medium. Customer is complaining that dashboard has non-functional items enabled.

This appears due to cinder policy not allowing for retrieving all consistency groups.

It turns out that this is a regression which was fixed in mitaka dashboard, but with updated policies, the fix no longer works in Queens.

Reference for old issue.

Note that this would require charm config enable-consistency-groups=True. I just came across this bug when looking into https://bugs.launchpad.net/bugs/1841188.
