URL: https://github.com/apache/doris/pull/32726
## Proposed changes
Add `ExternalTransactionManager` and `Transaction`.
`ExternalTransactionManager` is used to manage all external transactions:
```
class ExternalTransactionManager {
...
Map<Long, Transaction> transactions;
...
}
```
The application layer should manage the entire transaction through this
`ExternalTransactionManager`, like:
```
Env.getExternalTransactionManager().beginTransaction();
Env.getExternalTransactionManager().beginInsert();
Env.getExternalTransactionManager().finishInsert();
Env.getExternalTransactionManager().commit();
```
`Transaction` is an interface that unifies internal and external tables. It
currently implements external tables (`ExternalTransaction`) and will continue
to unify internal tables in the future.
For the `ExternalTransaction`, it mainly interacts with the external
metadata, so it will hold an `ExternalMetadataOps`.
Therefore, when the application layer calls a `Transaction` interface
through the `ExternalTransactionManager`, it will eventually be converted into
an operation on `ExternalMetadataOps`.
