When acquiring the `sqlserver` lock, it fails immediately if the lock can't be acquired. When running multiple migrations concurrently, only one of them will succeed and the other ones will fail. Wait for up to 10 seconds when acquiring the lock. This way it lets the other entity that has acquired the lock do its job first. This is consistent with what this library does for `postgres` (though it waits indefinitely) and for `mysql`.
