Upgrade Azure Blobstore fromi legacy azure-sdk (11.0) to latest (12.27.0)

Add azure storage blob 12.27.1 dependencies and upgrade the
azure blobstore.

Run Azurite-based integration tests against the latest Docker image
version, remove legacy.

Migrate to `com.azure:blobstorage:12.x`. The upgrade
tries to do a 1:1 migration to the new azure-sdk API (in its blocking
falvor) as much as possible, so that the integration tests serve to
avoid regressions.

A couple remarks:

* There's no way to close the HTTPClient so AzureClient does not
  implement Closeable anymore.
* Fix a bug in DeleteManager that always reported 0 objects deleted

Upgrade `com.microsoft.azure:azure-storage-blob` to
`com.azure:azure-storage-blob`.
