**Please do not merge until support for azure has been merged**

Adds the ability to ingest data from azure via the web console. There is now a tile that allows the user to access the Azure ingestion flow if druid-azure-extensions is in the load list. The default input type will be azure. The user can then put a can then input data using A URI or a Prefix. the resulting IO config changes will be :

  "ioConfig": {
    "type": "index_parallel",
    "inputSource": {
      "type": "azure",
      "prefixes": [
        "azure://containerName"
      ]
    }
  },

or

  "ioConfig": {
    "type": "index_parallel",
    "inputSource": {
      "type": "azure",
      "prefixes": [
        "azure://container-name/path-name.json"
      ]
    }
  },

The user can configure the rest of the spec using the normal web console flow.

Additionally
azure is now available as an input type in the input menu for all flows

I think you are referring to #9394 and it is merged!

There is no need for this upgrade spec clause, there was never a 'static-azure'. This is back compat code but Azure ingestion did not used to exist. You can just remove this change.

Same story as above.
