Add exception handling to CreateNode/ EditNode & CreateServer/ EditServer

[Boy132]

We probably want to add some more fine tuned exception handling at some point but for now this stops all 500 errors or silent errors and replaces them with a notification.

Looks good, I wonder if we should use traits for now?

Anyway we can catch the 500 on the create allocation, on the create server page?

Unless we just need to rewrite the logic, the port already exists... we should just skip over it, and present an error saying something along the lines of

Failed to Create Allocation
Failed to Create: :,

Wouldn't #395 fix/ change that anyways?

[notAreYouScared]

It would, but who knows when that would be done.

With latest changes 500's are still thrown when it skips the ports and does not return anything

Closing this for now. Will look into that later, probably.
