MVP for Central SCS Api

Created by: fkr

We want to build a MVP for a Central SCS Api.

Definition of Done:

• The architecture as well as the reasoning (aka: scope) of the MVP is clearly understood by the team
  • Single K8s Cluster for now, with tenancy via namespaces
• I (as a CSP) want to be able to onboard a customer to the central API (ideally but not necessarily using kubectl) - #372
• I (as a CSP customer) want to get a kubeconfig in order to access the central API (securely) - #373 using exec auth plugin that does OAuth2 Device Auth Flow
• I (as a CSP customer) want to kubectl apply VMs in OpenStack - #374
• I (as a CSP customer) want to kubectl apply a Kubernetes Cluster and get back a working kubeconfig (that enables me to talk to the created cluster) - #375
• I (as a CSP customer) want to kubectl apply an IdP identity federation to my (customer owned) IAM - #376
