[ui] Unable to remove Mongo node from deployed env

[Mike Scherbakov]

Steps to reproduce:
1) Deploy env with Ceilometer
2) Go to the nodes tab, choose MongoDB node, click on Remove. Status is changed to "pending removal".
3) Click on Deploy button

Expected result:
Node is remove, setting checkbox is unchecked. Or, notification is shown that I should uncheck Ceilometer in settings first, and then remove MongoDB node.

Actual result:
"When Ceilometer is enabled, environment should have Telemetery - MongoDB node" when I click on Deploy button. In Settings, Ceilometer checkbox is disabled (grayed), so I can't uncheck it.

I don't think diag.snapshot is required: it can be easily reproduced on fake UI: http://fuel-demo.mirantis.com:8000/

This bug conflicts with https://bugs.launchpad.net/fuel/+bug/1325710 Because we need to enable settings change after the deployment. So, what should be the workaround?

need answer to question above

Looks like it requires more work than just fixing a small issue.
The problem is that we need to re-run puppet on controller node, so it disables ceilometer.

We can then enable it on UI. Closing as Won't fix.
