Make the Managed Identity available from inside the cluster
We recently added User-Assigned Managed Identities to our HDInsight clusters, but were disappointed to find out that we can't use these MIs to access other resources such as Key Vaults.
Please expose the Managed Identity to the code running inside the cluster, to allow us to make our systems more secure.
P.S.: The workaround suggested in the docs (https://docs.microsoft.com/en-us/azure/hdinsight/hdinsight-managed-identities#hdinsight-managed-identity-implementation) is cumbersome, unclear (a concrete example would have helped here) and (if I understand it correctly) does not allow for easy certificate rotation.
