Alluxio file system should support sticky bit

Description

Sticky bit is useful in multiuser situations.

For example, if you were using Alluxio as default file system of spark on yarn, and got this warning: "Remote Root Log Dir /user/yarn_app_log already exist, but with incorrect permissions", from source code: LogAggregationFileController.java on line 268.

And it also very useful for the sharing directory like tmp
