Embedded ansible provider should allow creation in maintenance zone

[djberg96]

Currently you cannot create an embedded Ansible provider in the maintenance zone. Instead, this should be legal, though with the automation manager disabled.

You can see the current behavior here:

# RAILS_ENV=test bundle exec rails c
server = FactoryBot.create(:miq_server, :zone => Zone.seed)
provider = FactoryBot.create(:provider_embedded_ansible, :zone => Zone.maintenance_zone)

result: ActiveRecord::RecordInvalid (Validation failed: ManageIQ::Providers::EmbeddedAnsible::Provider: Zone cannot be the maintenance zone when provider is active)

This PR alters the ensure_managers method to allow it, setting the enabled attribute as appropriate.

Based on ManageIQ/manageiq-providers-ansible_tower#211

@bdunne, @agrare guess I need some help with this one. Thought it was passing locally, now it looks like the zone isn't getting created properly. What's the proper way to set this up?

[agrare]

I don't think :zone => Zone.seed is what you're looking for here. I think you want to add

MiqRegion.seed
Zone.seed

here before the assign_embedded_ansible_role(miq_server)
