File Storage CREATE API Operations Fail
File Storage API resource create operations such as createFileSystem fail to create resources.
Cause: High volume can cause API calls to fail. If you haven't specified
                retry in your request, the operation isn't tried again, and the
            resource isn't created.
Solution: Retry the API operation. Use the 
opc-retry-token header
            in the create resource request. For example:
            POST /20171215/fileSystems
Host: filestorage.us-phoenix-1.oraclecloud.com
opc-retry-token: 239787fs987
