Nunjucks templated values don't update in UI

[jjo93sa]

Appliance properties displayed in the UI via nunjucks templates don't update when the appliance is updated. For example, we allow the user to update the number of IPUs their machine has available. If the user changes the number, and updates the appliance, the new IPU count isn't displayed in the UI (the IPU count is also populated into the instance metadata, and is correctly updated there).

There appears to be nothing the user can do to force an update: refreshing the details pane doesn't help; refreshing the main dashboard page doesn't help; logging out and back in doesn't help.

Another case where this seems to happen: when an appliance deployment fails, and the user "patches" the cluster as instructed in the error message. If the appliance successfully builds, the UI stubbornly displays out-dated or default/ placeholder text.
