Loading backends of a link backend is slow #586
Description
Problem
On Nuvolat i'm trying to add a new linked backend to one of the globalbackend but loading the backends of NY2 is very slow.
The call to NY2 returned a valid json with the information of the backends.
response:

@jeroenmaelbrancke please define very slow. Are we talking about 5s, 30 secs, 5 mins or even longer?

Had a talk with @JeffreyDevloo about this one and this might be cause by the dynamics (f.e. whether or not a policy can be met).
Since it will always be OPS who will perform these kind (link backend, ...) of tasks, it would make sense to be less strict as OPS knows/should know what that are doing and whether it is safe to do so. Also if things fail, they have the knowledge to check what went wrong.

If you say (100% sure) only OPS will perform these tasks than i'm happy with it.

Calling the API directly would already speed things up as the GUI does additional checks.
