Review Comment:
Restore job need to read BackupMeta from a file, which is downloaded from
repo into a temp dir in FE.
When reading, it specifies the meta version, which is used on the backup
doris cluster.
From example,
we backup data from a 2.1 doris, which meta version is lower or equal than
129.
Then we restore data to a 3.0 cloud doris,
In cloud mode, EnvFactory.getInstance().createPartition() will create a
CloudPartition,
this will causes the read function failed.
If we found the meta version here is lower than 129, which means it is
absolutely should not return a CloudPartition, We can return a Partition here.
