A Host::Base can be a Host::Managed if it's managed? attribute is set. When managed? is false, the host should no longer be a Host::Managed. In nightly, this is not the case.

To reproduce (in rake console):
h = Host.new
h.managed? # false

Actual:
h.class # Host::Managed

Expected:
h.class # Host::Base

This is an issue if we ever want to use polymorphism, and it should be as easy as setting the type correctly on the host. Hopefully, there is no behavior on Host::Managed that shouldn't be there, but if so, it should be moved to Host::Base.
