Node cannot join the cluster due to expired bootstrap token

[schrodit]

How to categorize this issue?

/kind bug
/priority 3

What happened:
Mostly always my machines take more than 20 minutes to be created in the cloudprovider.
Therefore the workers are configured to with a specific machineCreationTimeout of 50m.
When the nodes come up after approx. 30min the node is unable to join cluster due to a expired bootstrap token.

What you expected to happen:

Bootstrap token for node does not expired before the configured spec.worker[].machineController.machineCreationTimeout

How to reproduce it (as minimally and precisely as possible):

1. Create a shoot and configure a worker group with a machineCreationTimeout of more than 20m
2. let the machine need more than 20 minutes to be created
