import_facts assumes orchestration is available
Currently (core:develop, discovery:develop) provisioning a discovered host isn't possible. The `import_facts` method assumes there are two methods defined, enable_orchestration! and skip_orchestration! which do not exist for Host::Discovered.
This causes Foreman to throw the following error "undefined method `enable_orchestration!' for #<Host::Discovered:0x005623782265b8>". This is also true when importing facts for a host with :unattended => false
Host::Discovered doesn't need the Orchestration module for anything, however `import_facts` assumes it's there. This should involve two fixes:
1: in discovery, so that it can skip those calls (mocking them or something).
2: in core, so that import_facts doesn't have to rely on anything but Host::Base APIs. It should "know less", and let Host::Managed do these things (enable/skip orchestration) perhaps, as that's where it matters.
The code that causes this error will go in 1.12.1 https://github.com/theforeman/foreman/pull/3574/files#diff-07cbb99bfdb4bed86ad02486bb5adde2R174 so we should hurry up and release a version that fixes the problem. http://projects.theforeman.org/issues/15306
Fixes #15644 - Move enable/skip_orchestration to Host::Managed
skip_orchestration and enable_orchestration were called in Host::Base
when importing facts. These two methods could not be called there
because they come from the Orchestration mixin which Host::Base does not
have. This blocked importing facts for a Host::Discovered or a Host::Base.
To test this, I've moved the tests that import the facts to a separate
test class just for Host::Base. Notice I've moved a few other tests
which also belong there. There are probably more, but I didn't want to
make this more complicated.
Lastly, Nic::Managed called lookup_value_match on save, so importing
facts didn't work for Host::Base as that method wasn't there either, so
I moved it. Same logic applies to 'setup_clone'.
