wujinhu updated HADOOP-15158:
-----------------------------
    Description: 
Currently, AliyunCredentialsProvider supports credential by 
configuration(core-site.xml). Sometimes, admin wants to create different 
temporary credential(key/secret/token) for different roles so that one role 
cannot read data that belongs to another role.
So, our code should support pass in the URI when creates an 
XXXCredentialsProvider so that we can get user info(role) from the URI
