setTier(tier, options) {
        return this.client.sendOperationRequest({ tier, options }, setTierOperationSpec);
    }
The Set Tier operation sets the tier on a blob. The operation is allowed on a page blob in a premium
storage account and on a block blob in a blob storage account (locally redundant storage only). A
premium page blob's tier determines the allowed size, IOPS, and bandwidth of the blob. A block
blob's tier determines Hot/Cool/Archive storage type. This operation does not update the blob's
ETag.
@param tier Indicates the tier to be set on the blob.
@param options The options parameters.
