Bumping dedicated cluster cku # forces replacement of cluster

[egor-georgiev]

Recently I've tried to bump number of ckus, as well as network ingress and egress for a cluster (otherwise confluent would reset the latter two parameters and I'll be forced to replace as well), and I got a message that my cluster will get replaced. In Confluent UI, it is possible to upgrade ckus for a dedicated cluster without destruction. Is it possible for the provider to match functionality, or does this one depend on the confluent client?

• TF version: 0.13
• provider version: 0.0.14
