Currently, when reading a hive on cosn table, doris return empty result, but the table has data.
iceberg on cosn is ok.
The reason is misuse of cosn's file sytem. according to cosn's doc, its fs.cosn.impl should be org.apache.hadoop.fs.CosFileSystem

1. Fix iceberg catalog bug

    This PR apache#30198 change the logic of `IcebergHMSExternalCatalog.java`,
    to get locationUrl by calling hive metastore's `getCatalog()` method.
    But this method only exists in hive 3+. So it will fail if we using hive 2.x.

    I temporary remove this logic, because this logic is only used from iceberg table writing.
    Which is still under development. We will rethink this logic later.

2. Fix test cases

    Some of P2 test cases missed `order_qt`. And because the output format of the floating point
    type is changed, some result in `out` files need to be regenerated.

Fix Reach limit of connections error
in fe.conf , arrow_flight_token_cache_size is mandatory less than qe_max_connection/2. arrow flight sql is a stateless protocol, connection is usually not actively disconnected, bearer token is evict from the cache will unregister ConnectContext.

Fix ConnectContext.command not be reset to COM_SLEEP in time, this will result in frequent kill connection after query timeout.

Fix bearer token evict log and exception.

…ollecting table in plan (apache#32797)

Support to get tables in materialized view when collecting table in plan

table scehma as fllowing:

create materialized view mv1
BUILD IMMEDIATE REFRESH COMPLETE ON MANUAL
DISTRIBUTED BY RANDOM BUCKETS 1 
PROPERTIES ('replication_num' = '1')
 as 
select 
  t1.c1, 
  t3.c2 
from 
  table1 t1 
  inner join table3 t3 on t1.c1 = t3.c2

if get table from the plan as follwoing, we can get [table1, table3, table2], the mv1 is expanded to get base tables;

SELECT 
  mv1.*, 
  uuid() 
FROM 
  mv1 LEFT SEMI 
  JOIN table2 ON mv1.c1 = table2.c1 
WHERE 
  mv1.c1 IN (
    SELECT 
      c1 
    FROM 
      table2
  ) 
  OR mv1.c1 < 10

)

Add table version to cloud.

In Fe:
Get: If Fe is cloud mode, get table version from meta service.
Update: Op drop/replace temp partition, commit transaction.

In meta service:
Add: create Index. init value is 1.
Remove: by recycler.
Update: commit/drop partition rpc, commit txn rpc. Atomic++.

1. Use equals instead of == for type comparing
2. null bitmap size is reisze by size of ref column.
