Disable request throttling in S3BlobStoreRepositoryTests (#46226)

When some high values are randomly picked up - for example the number 
of indices to snapshot or the number of snapshots to create - the tests in S3BlobStoreRepositoryTests can generate a high number of requests to 
the internal S3 server.

In order to test the retry logic of the S3 client, the internal server is 
designed to randomly generate random server errors. When many
 requests are made, it is possible that the S3 client reaches its maximum 
number of successive retries capacity. Then the S3 client will stop 
retrying requests until enough retry attempts succeed, but it means 
that any request could fail before reaching the max retries count and 
make the test fail too.
