Deleted plugin remains available in cluster settings

[Kyrylo Romanenko]

Steps:
1. Deploy Fuel environment.
2. Install LDAP plugin.
3. Create a cluster by wizard.
4. Enable "LDAP plugin for Keystone" in Settings.
5. Disable "LDAP plugin for Keystone" in Settings.
6. Delete plugin from fuel node.
7. Re-login to Fuel UI. Select same cluster and proceed to Settings.
Notice that Plugin still exists in settings menu and you can still enable and disable it by checkbox and "Save Settings" button.
Only in new created clusters that obsolete plugin will be absent.
Attempt to deploy cluster with enabled removed plugin gives no warnings and proceeding deployment.

hello fuel-ui team, please take a look into the report. It seems to be related with UI.

Otherwise, don't hesitate to pass it to another team such as fuel-python or fuel-plugins.

Hi, this is an old and known issue - options from plugin environment_config.yal remain in db after plugin deletion and thus visible in UI
