starrocks [Feature] COS posix bucket support

Why I'm doing:

What I'm doing:

This PR adds the support of COS posix bucket. With broker, you can use Broker Load to load data from COS posix bucket, and use SELECT INTO OUTFILE to export data to COS posix bucket. This is maily inspired by https://cloud.tencent.com/document/product/436/82208.

LOAD LABEL db0.label3 (     DATA INFILE("cosn://xxx/some.parquet")     INTO TABLE tbl_student     FORMAT AS "parquet"     (name, age)  ) WITH BROKER  srbroker ( 
"fs.cosn.bucket.endpoint_suffix" = "cos.ap-guangzhou.myqcloud.com",
"fs.cosn.userinfo.region"="ap-guangzhou",
"qcloud.object.storage.ranger.service.address"="10.0.0.26:9999",
"hadoop.security.authentication"="kerberos",
"fs.ofs.tmp.cache.dir"="/tmp","fs.cosn.trsf.fs.ofs.user.appid"="12345",
"qcloud.object.storage.kerberos.principal"="hadoop/10.0.0.26@EMR-ABC",
"kerberos_principal"="hadoop/10.0.0.26@EMR-ABC", 
"kerberos_keytab"="/var/krb5kdc/emr.keytab"
);

SELECT * FROM tbl_student INTO OUTFILE "cosn://some_bucket/parquet/" FORMAT AS PARQUET PROPERTIES (
"broker.name"="srbroker",
"fs.cosn.bucket.endpoint_suffix" = "cos.ap-guangzhou.myqcloud.com",
"fs.cosn.userinfo.region"="ap-guangzhou",
"qcloud.object.storage.ranger.service.address"="10.0.0.26:9999",
"hadoop.security.authentication"="kerberos",
"fs.ofs.tmp.cache.dir"="/tmp","fs.cosn.trsf.fs.ofs.user.appid"="12345",
"qcloud.object.storage.kerberos.principal"="hadoop/10.0.0.26@EMR-ABC",
"kerberos_principal"="hadoop/10.0.0.26@EMR-ABC", 
"kerberos_keytab"="/var/krb5kdc/emr.keytab"
);
