New Features

"gRPCCall" logs on standard output now include "fullError" with complete error structure. Typically, it contains "code" and "message" with gRPC error. (#254, @jsafrane)
The CSI mock driver behaviour can be tweaked with JavaScript hooks in the CSI calls. (#251, @tsmetana)
Added (optional) repeated operations to test idempotency. (#229, @okartau)
csi-sanity --csi.testvolumeaccesstype=block now runs CSI tests with raw block volumes. (#246, @taaraora)
Add NodeUnpublishVolume test for when the volume is missing. (#242, @timoreimann)
sanity.NewTestContext is now exported, which simplifies writing custom tests that reuse the sanity testing infrastructure. (#253, @pohly)
Topology support can be enabled in the CSI mock driver with -enable-topology. (#249, @pohly)

Bug Fixes

The CSI mock driver now returns OK for requests to detach a deleted volume, as expected by current external-attacher. (#250, @pohly)
