[sc-5307] - add support to all auth providers in k8s clientset

[maxlevinps]

What this PR does / why we need it: oidc auth provider support was missing when creating k8s clientset, so in this pr we've added:

_ "k8s.io/client-go/plugin/pkg/client/auth"

which imports all auth providers plugins, so we will now support:

• azure
• exec
• gcp
• oidc
• openstack

Which issue(s) this PR fixes:
