[csi] Add field ActualLVNameOnTheNode. Add SDSLocalVolumeCSIFinalizer. Add delete LVMLogicalVolume after error in CreateVolume. Bump go builder to 1.21

[AleksZimin]

Description:

This PR introduces several enhancements and fixes:

• ActualLVNameOnTheNode Field: Synchronized the ActualLVNameOnTheNode field in the LVMLogicalVolume spec with the design documentation to ensure consistency.
• SDSLocalVolumeCSIFinalizer: Implemented a dedicated finalizer for CSI within LVMLogicalVolume to prevent the deletion of Logical Volumes (LV) on nodes if the CSI finalizer has not been removed. This addition aims to enhance the management and cleanup of resources.
• Deletion of LVMLogicalVolume on CreateVolume Error: Added logic to delete the LVMLogicalVolume resource if an error occurs during the CreateVolume operation, improving error handling and resource cleanup.
• Go Builder Version Bump to 1.21: Updated the Go builder version to 1.21 to leverage new Go features and improvements.

What is the expected result?

• Improved consistency between the LVMLogicalVolume spec and design documentation.
• Enhanced resource lifecycle management with the new finalizer, preventing premature LV deletions.
• Better error handling through automatic cleanup of resources upon failure in volume creation.
• Utilization of Go 1.21 features for development, resulting in more efficient and reliable code.

Checklist:

• The code is covered by unit tests.
• e2e tests passed.
• Documentation updated according to the changes.
• Changes were tested in the Kubernetes cluster manually.
