High availability for connecting Kyma runtime with Compass (UCL)

[pbochynski]

Description Ensure that connection to Unified Customer Landscape (UCL) based on open source project compass can be established regardless of the UCL availability (eventually) also in the bring your own cluster model (BYOC).

Reasons Currently, the connection between the runtime agent and UCL is initialized by the runtime provisioner. Provisioner connects to the compass director registers runtime and then creates a one-time token as a secret in the runtime. The main disadvantages are:

• in case of UCL unavailability Kyma runtime provisioning fails (even for customers who do not want to use application connectivity)
• Kyma installations on customer own clusters (not proviosioned by Kyma) do not have connection to the UCL (application connector doesn't work there)

High level architecture proposal

The solution introduces a new controller in the contol plane (compass-manager). The controller can watch Kyma resource in the control plane (created for each Kyma installation, also for BYOC model). In the first phase controller will create one-time token for each Kyma cluster. Later on, when application-connector modularization is completed the token can be created only for those clusters where module is enabled.
