v19.07.0

Changes since v19.04.0

Fixes:

• Kubernetes: Improved volume import transaction cleanup during failure scenarios.
• Kubernetes: Fix unknown backend states after Trident upgrade.
• Kubernetes: Prevent operations on failed backends.
• Kubernetes: Removed size requirement for volume import PVC file.

Enhancements:

• Trident driver for Azure NetApp Files.
• Kubernetes: Implemented CSI Trident (optional for Kubernetes 1.13, exclusive for Kubernetes 1.14+).
• Kubernetes: Added support to CSI Trident for volume snapshots.
• Kubernetes: Converted Trident to use custom resource definitions instead of etcd.

  parameter to false in ONTAP SAN backend's default config section would disable the space-allocation feature for
  those LUNs.
