v1.4.0-rc1

Merge pull request #470 from pohly/maximum-volume-size

GetCapacityResponse: add maximum_volume_size

v1.3.0

Breaking changes/Deprecations:

• There are plans to deprecate Volume Expansion "online/offline" capability (moving to online by default, while allowing for offline via the "Volume In Use" error code). These changes are NOT being made in this CSI release (CSI v1.3.x), instead they will most likely be part of the next minor release (CSI v1.4.x). If you depend on "offline/volume expansion" please follow the relevant discussions (e.g. #429, #431, etc.), and read the CSI 1.4.x release notes carefully.

Additions:

• spec (PR #417): Introduce alpha protobuf annotations to enable new APIs to be introduced experimentally before evolving to something more stable. Note that Alpha APIs may change in incompatible ways or be removed between minor releases without notice.
• spec (PR #415): [Alpha] Introduce a new VOLUME_CONDITION controller and node capability along with new ControllerGetVolume call and new volume_condition fields in ListVolumesResponse to enable CO to periodically probe a provisioned volumes health status.
• spec (PR #412): Add additional reason to return ALREADY_EXISTS for CreateVolumeRequest.
• spec (PR #422): Add Nomad to Container Orchestrators who've adopted CSI.

Clarifications/Corrections/Fixes:

• spec (PR #397): Clarify idempotency requirement for ControllerExpandVolume and NodeExpandVolume.
• spec (PR #406): Clarify the sources of volume_context.

Dependencies:

• spec (PR #438): Pin go-genproto and grpc-go versions to 24fa4b261c55da65468f2abfdae2b024eef27dfb to ensure compatiblity with protobuf v1.3.2

Additions:

• spec (PR #374): Add optional (but recommended) VolumeStatus.published_node_ids field to ListVolumesResponse (to enable COs to detect and reconcile when a volume is unpublished out of band).
• spec (PR #390): Add optional (but recommended) staging_path to NodeGetVolumeStatsRequest and NodeExpandVolumeRequest.
• spec (PR #381): Add optional volume_capability to ControllerExpandVolumeRequest and NodeExpandVolumeRequest (to enable SPs to differentiate between block and file).

Clarifications/Corrections/Fixes:

• spec (PR #347): Clarify DeleteVolume behavior with snapshots.
• spec (PR #375): Clarify SP is allowed to return OK for ControllerUnpublishResponse if node or volume not found.
