Description

Currently all `CREATE_DISK` and `DESTROY_DISK` operations will be dropped when SLRP is reconciling its storage pools with the CSI plugin. If the reconciliation ends up with new storage pools showing up, then all incoming operations will also be dropped because of a resource version change. This leads to bad user experience and make it hard to write tests, so we should try to avoid dropping operations.

 

This is extremely painful for testing, because we need to ensure that SLRP finishes profile updates before issuing operations.
