providing CA certs to containers for ext-DB

[evgeni]

When running ext-DB, people should use SSL, but for that we need a way to pass in the CA cert (which might be different than the Foreman one!)

Is this convered by https://github.com/theforeman/foreman-quadlet/blob/master/docs/parameters.md#mapped with --database-ssl-ca ?

[evgeni]

If it works, yeah!

it did not, but #345 fixed it :)
