Description
Today users of snapshot repositories backed by Azure Blob Storage cannot specify which access tier to use, so Elasticsearch will use the account-level default tier for all uploads. We should give users the ability to tell Elasticsearch to specify a particular storage tier at upload time rather than using the account-level default. For similar reasoning to that described in #81352 we should make this separately configurable for data and metadata blobs. In addition, we should allow users to specify tags for Elasticsearch-related uploads so that they can apply a lifecycle policy to their snapshot data. Again, users should be able to specify different tags for data and metadata blobs so that these datasets can have different lifecycle policies.
