VPC RC keeps crashing during cache build stage on clusters with high CRDs

[jaydeokar]

Describe the Bug:

VPC-RC crashes during initialization when there are high number of CRDs in the cluster. VPC-RC on startup tries to build the client cache by making calls to API server. If the time required to build the cache is >90 secs, the controller goes into a restart loop as that's the LivenessProbe configured for the controller.

Observed Behavior:
Controller keeps restarting while trying to build the cache.

Expected Behavior:
Controller should not crash during initialization.

How to reproduce it (as minimally and precisely as possible):
Have large number of CRDs ( >1000 ) and restart the controller. It should show client side throttling messages in the logs and a considerable time in building the cache

Additional Context:

Environment:

• Kubernetes version (use kubectl version):
• CNI Version
• OS (Linux/Windows):
