Clustering with allow update strategy could fail w/ async clustering

with async clustering and allow update strategy, there could be failures in the pipeline. You can check out the below stacktrace. 

here is the condition when this is possible. When we are looking to support updates when clustering is in progress, we might have to consider this scenario. 

A file group FG1 was chosen to be replaced by clustering plan. And clustering is in progress. At this juncture, if we get a new batch of upserts and after index look up, if records are tagged w/ FG1, and before merge handle for upsert is called, lets say clustering is completed. So, when getting latest base file for FG1, FileSystemView might return none since the FG has been replaced (since clustering is completed). So, when are looking to add update support w/ async clustering, we might have to support this use-case as well. But its a low priority ticket for now, since with allow update strategy we do claim that there could be data loss and on one is supposed to try out in production setting for now.

## JIRA info

- Link: https://issues.apache.org/jira/browse/HUDI-3846
- Type: Task

Start with BaseSparkCommitActionExecutor.java and HoodieMergeHandle.java, following the update path from handleUpsertPartition through getUpdateHandle. Inspect how FileSystemView resolves the latest base file when clustering replaces a file group during an async update. Done means this race no longer throws NoSuchElementException for the described scenario.
