I'd suggest to add the host_provider_id field to vdsStatic in order to accomplish that.

This looks like a code change and it seems there is nothing to be tested here. If you think otherwise, please provide steps to reproduce.

testcase:
Go to engine, add host by external provider.
check the provider id in db (select * from providers) and check that the value correlates to the value in vds_static::host_provider_id (select host_provider_id from vds_static;)

except that, check that host which added regularly gets none in its host_provider_id column.

host_provider_id is empty in vds_static:
select vds_name,host_provider_id from vds_static ;
 vds_name | host_provider_id 
----------+------------------
 host1    | 
(1 row)
