Allow to create container/vms even if one promox nodes is offline

[jacac]

Issue

When creating a container and one or more nodes in the cluster are offline an error is displayed and no actions are allowed.

Suggestion

It should remove those nodes from the selection and display and warning that some nodes are currently available.

I would like this option as well. The plug in should not try to query status on offline or nodes that in maintenance. In my case i had a node offline that i'm not using and while trying to query the node, the request failed.
