Allow users with 'cloud_dns_ops' role to assign other (less privileged) DNS roles to users

[galkindmitrii]

This is a bit tricky feature request from GNS DNS. The DNS role hierarchy will soon look like:

cloud_dns_admin (the most privileged) cloud_dns_ops cloud_dns_support dns_zonemaster dns_hostmaster dns_mailmaster dns_webmaster dns_viewer (the least privileged; read-only access)

Where only dns_viewer and dns_webmaster roles will be assignable via Elektra project dashboard.

Now, for GNS it will be helpful if people with cloud_dns_ops role could also assign all DNS roles under (i.e. cloud_dns_support; dns_zonemaster; dns_hostmaster; dns_mailmaster; etc) to other users.
