Support hive external table on Ali oss.

[Jibing-Li]

Proposed changes

Provide support for hive external table on Ali oss. Create table:

CREATE TABLE `test` (   `k1` integer NOT NULL,   `k2` integer NOT NULL,   `k3` integer ) 
engine=hive properties 
("database"="default", 
"table"="test2", 
"hive.metastore.uris"="thrift://host:port"
"AWS_ACCESS_KEY" = "YOUR_ALI_ACCESS_KEY",
"AWS_SECRET_KEY" = "YOUR_ALI_SECRET_KEY",
"AWS_ENDPOINT" = "YOUR_ALI_ENDPOINT",
"AWS_REGION" = "YOUR_ALI_REGION");

select result:

MySQL [test]> select * from test;
+------+------+------+
| k1   | k2   | k3   |
+------+------+------+
|    1 |    2 |    3 |
+------+------+------+
1 row in set (0.55 sec)

是支持的，但fe端hadoop文件系统api不支持oss://开头的路径，需要替换成s3://
