### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
### Description
For high throughput scenarios, after turn on the local_replica_selection, the performance improvement is obvious.
But local_replica_selection have a problem, all frontends can only use local replicas to do the query, so even if the be fails for a short time, a large number of queries will fail.
A reasonable solution is to select a non-local BE to service the query when the local be is unavailable, whether to fallback to non-local BE could be control by configure.
