CSI volume shows controller health as unhealthy even when no controller is needed

[apollo13]

Nomad version

0.12.5

Issue

The Storage -> Volume tab says unhealthy for controller health for my CSI plugin:

Since my plugin does not require a controller, it would be great if the UI could give one the benefit of the doubt if no controller is running. After all it lists it as Schedulable which probably wouldn't work either if a healthy controller were a requirement :)

Reproduction steps

Use any CSI plugin that does not need a controller.

Thanks for noticing this @apollo13. Definitely something that'd be nice to polish up.

@apollo13 I was able to reproduce this with a node-only plugin. The screenshot below is the AWS EFS plugin on Nomad 0.12.7:

Whereas the plugin tab shows it correctly:

The API includes a field ControllerRequired which the web UI uses to gray-out that field if one isn't required. So that's not getting referenced in that volume tab for some reason. Should be a small fix.
