Update GardenerCluster CRD printed columns

[m00g3n]

Description

Update GardenerCluster CRD printed columns to show information about CR state, runtime-id and shoot-name.
E.g.

$ kubectl get gardenerclusters.infrastructuremanager.kyma-project.io -A
NAMESPACE    NAME         STATE   RUNTIME-ID   SHOOT-NAME   AGE
kcp-system   runtime-id   Ready   runtime-id   shoot-name   2m40s

Changes proposed in this pull request:

• STATE and RUNTIME-ID columns added

Please add also the AGE field and kyma-project.io/shoot-name

on DEV (that runs on latest d79e85b), I can still see the old way of printing:

[･‿･] ~ kubectl get gardenerclusters -n kcp-system
NAME         AGE
a5c9b4e      171m
bf3485c      4d23h
c-1ef5961    4d23h
c-28b39a2    171m
c-38414f2    171m
c-3acbdd1    4d23h
c-5287766    4d23h
c-61b5087    4d23h
c-67fae28    171m
c-91c8454    171m
c-939e9b0    4d23h
c-97b785b    4d23h
c-9c16d48    4d23h
c-9d85254    4d23h
d3d2dd1      4d23h
runtime-id   45h
[･‿･] ~ kubectl get gardenercluster -n kcp-system a5c9b4e
NAME      AGE
a5c9b4e   171m

Now it works

kubectl get gardenerclusters -n kcp-system
NAME         STATE   RUNTIME-ID                             SHOOT-NAME   AGE
