What this PR does / why we need it:
There are use-cases in which the default options for
client.Clientandcluster.Clusterwith just theSchemeset are not sufficient. This PR introduces the possibility to arbitrarily modify both options when working with theclusterspackage.As a side effect, calling
InitializeRESTConfig()andInitializeClient(...)multiple times is now not a no-op anymore, but actually re-loads the config and re-creates cluster and client, respectively.Special notes for your reviewer:
Required for the ClusterProvider: Gardener.
