Enable short circuit even domain socket is configured
### Background
I found short circuit has better performance than domain socket. But
when i enable short-circuit read/write, alluxio client prefer to use
domain socket as default.
I want to use short-circuit read/write, even domain socket is ready in
AlluxioWorker.
### Discussion
I use a new property `alluxio.user.short.circuit.preferred` to control
the logic, which is backward compatible.
But i think it is better to use only
`alluxio.user.short.circuit.enabled` to judge whether to enable short
circuit.
