Breaking change

As part of our effort to withdraw support for MySQL and SQLite, if you start BTCPay Server with --sqlitefile or --mysql without being in the context of a migration, your server will fail to start.

We introduce another flag, --deprecated, which allows you to start with SQLite or MySQL even if it is deprecated. We will remove this flag in version 1.10.
