create-essential-database
Create a new essential database inside the specified subscription ID. Returns a TASK ID that can be used to track the status of the database creation. IMPORTANT GUIDELINES: 1) DO NOT set optional parameters unless explicitly requested. 2) Modules can only be selected if protocol is 'redis'. 3) When creating a free database, first call the get-essential-subscriptions tool to check if a free database already exists (each account is limited to one free database). 4) For database modules, validate against get-database-modules list. 5) The payload must match the input schema.
