Generates a reversible Ecto migration that installs AuditLog:
mix audit_log.gen.migration
mix audit_log.gen.migration -r MyApp.RepoThe task passes all options to mix ecto.gen.migration. For example, use
--migrations-path to select a custom directory.
The generated migration calls AuditLog.Migration.up/1 and
AuditLog.Migration.down/1. Edit those calls to add a PostgreSQL schema
prefix when needed.
