Integration with Spatie packages

laravel-activitylog

For the tenant app:

• Set the database_connection key in config/activitylog.php to null. This makes activitylog use the default connection.
• Publish the migrations and move them to database/migrations/tenant. (And, of course, don't forget to run artisan tenants:migrate.)

For the central app:

• Set the database_connection key in config/activitylog.php to the name of your central database connection.

laravel-permission

Install the package like usual, but publish the migrations and move them to migrations/tenant:

php artisan vendor:publish --provider="Spatie\Permission\PermissionServiceProvider" --tag="migrations"
mv database/migrations/*_create_permission_tables.php database/migrations/tenant

Then add this to your AppServiceProvider::boot() method:

tenancy()->hook('bootstrapped', function (TenantManager $tenantManager) {
    \Spatie\Permission\PermissionRegistrar::$cacheKey = 'spatie.permission.cache.tenant.' . $tenantManager->getTenant('id');
});

The reason for this is that spatie/laravel-permission caches permissions & roles to save DB queries, which means that we need to separate the permission cache by tenant.
