Delta Lake Extension for Druid: Missing Support for Azure and ADLS Integration

### Motivation

Delta lake extension does not work azure.

### Proposed changes

Add azure support for delta lake.
Add a proper documentation for azure delta lake and delta tables

### Rationale

Delta Lake extension is limited to aws

The issue names the Delta Lake extension and its existing AWS limitation, but no files or tests. Start by locating that extension and reviewing how its AWS integration is configured, then determine the Azure/ADLS support and documentation scope. Done means Azure Delta Lake and Delta table use cases work and are documented.
