Application Connector - Events are not received after installation

[koala7659]

Description

After fresh installation application connector module is unable to receive events until Application are synchronised with Compass which takes about 10 minutes after installation.

It is most likely caused by the reconciliation algorithm in the compass-runtime agent.
Normally when compass-runtime-agent service was running from the moment when Kyma Runtime was installed this effect was hardly visible.

When application instance is missing the event received from it is rejected by the connectivity-validator service:
