mod_auth_cyrus: Add empty 'profile' table to SASL handler objects This is for compatibility with Prosody's built-in util.sasl objects. A SASL profile table usually includes methods supported by the backend, which can be used by SASL mechanism handlers to perform operations (such as testing the password). It also optionally contains a 'cb' field with channel binding method handlers. The Cyrus backend doesn't support channel binding, and doesn't have the same concept of auth backend methods (it handles all that internally, and Prosody has no insight or control over it). Thus, we create an empty profile which informs Prosody that the SASL handler does not support any of the auth or channel binding methods. Some features will not work, but they didn't work anyway. This just makes it explicit. This fixes a traceback in mod_sasl2_fast, which expected SASL handlers to always contain a 'profile' field.

::: {.alert .alert-danger}
This storage driver is fully async and requires that all storage access happens in an async-compatible context. As of 2023-10-14 this work in Prosody
is not yet complete. For now, this module is primarily suited for testing and finding areas where async work is incomplete.

This module provides storage in Amazon S3 compatible things. It has been tested primarily with MinIO.

``` lua
s3_bucket = "prosody"
s3_base_uri = "http://localhost:9000"
s3_region = "us-east-1"
s3_access_key = "YOUR-ACCESS-KEY-HERE"
s3_secret_key = "YOUR-SECRET-KEY-HERE"
