CI Failures: AzureBlobStoreRepositoryTests.testIndicesDeletedFromRepository

[nknize]

This test has failed periodically (but consistently):

https://groups.google.com/a/elastic.co/forum/#!searchin/build-elasticsearch/AzureBlobStoreRepositoryTests$20testIndicesDeletedFromRepository%7Csort:date

I have not been able to reproduce but (like #47380) it also looks like its coming from the Azure plugin:
