disableFileTransferRebalance API is not intuitive

There is a new API for disabling the File Transfer Rebalance for FTS:

curl -XPUT -H "Content-type:application/json" http://<Administrator>:<pwd>@<node>:8094/api/managerOptions -d '{"disableFileTransferRebalance": "false"}'  

The operation of this API might be a little difficult to understand as it doesn't operate in the same way as other APIs that we use.

The main problem is that we are switching something on by setting a value to false.

It is suggested that the API is replaced (or a new one added) that does the same thing but in a way that would be easier to understand.

{"fileTransferBalanceEnabled" : "false"}
