Breaking API change in AWS CVS affects Trident 19.07

[clintonk]

SDE 1.126.1 rolled out very recently.

Prior to this version, this volume creation worked fine:

POST https://cv.eu-west-2.netapp.com:8080/v1/FileSystems
 
{"name":"testvol1234567890","region":"eu-west-2","creationToken":"cvs-testvol1234567890","exportPolicy":{"rules":[{"allowedClients":"0.0.0.0/0","cifs":false,"nfsv3":true,"nfsv4":true,"ruleIndex":1,"unixReadOnly":false,"unixReadWrite":true}]},"labels":["{\"trident\":{\"version\":\"19.10.0-custom+unknown\",\"platform\":\"docker\",\"platformVersion\":\"18.09.0\",\"plugin\":\"aws-cvs\"}}"],"protocolTypes":["NFSv3","NFSv4"],"quotaInBytes":100000000000,"securityStyle":"unix","serviceLevel":"standard","snapshotPolicy":{"dailySchedule":{"hour":0,"minute":0,"snapshotsToKeep":0},"enabled":false,"hourlySchedule":{"minute":0,"snapshotsToKeep":0},"monthlySchedule":{"daysOfMonth":"1","hour":0,"minute":0,"snapshotsToKeep":0},"weeklySchedule":{"day":"Sunday","hour":0,"minute":0,"snapshotsToKeep":0}}}

With 1.126.1, the same call fails:

Code: 400. Message: Error creating file system - NFSv4 is not supported

Fix forthcoming...
