### Description of PR
JIRA: YARN-11509. The FederationInterceptor#launchUAM Added retry logic.
There is a "todo" in the
FederationInterceptor#registerAndAllocateWithNewSubClusters method. According
to the "todo" description, the request needs to be retried to other
subclusters, but changing the parameter requests in
registerAndAllocateWithNewSubClusters is not a good operation. It is better to
add retry logic here.
We don't need to worry about losing requests because when the request cannot
be satisfied, the AM of the task will continue to apply, and these requests
will be properly transferred to other clusters for execution.
