Error message for timeout errors during app create/update.

[kvmw]

When a service instance create/update operation fails, due to timeout errors, the last operation message is empty.

Showing status of last operation:
   status:    update failed
   message:
   started:   2024-09-26T14:04:45Z
   updated:   2024-09-26T14:04:45Z

Maybe having a message like "timeout waiting for deployment/staging/startup/..." or such can help users, without the need to check the logs.
