W. Trevor King 432f28355a *: Make libvirt support completely conditional (behind TAGS=libvirt)
Previously, destroy support was behind TAGS=libvirt_destroy and create
support was always built in.  But since 3fb4400c (terraform/plugins:
add `libvirt`, `aws`, `ignition`, `openstack` to KnownPlugins,
2018-12-14, #919), the bundled libvirt Terraform provider has also
been behind libvirt_destroy.  That leads to cluster creation failing
with:

  $ openshift-install create cluster
  ...
  ERROR Missing required providers.
  ERROR
  ERROR The following provider constraints are not met by the currently-installed
  ERROR provider plugins:
  ERROR
  ERROR * libvirt (any version)
  ERROR
  ERROR Terraform can automatically download and install plugins to meet the given
  ERROR constraints, but this step was skipped due to the use of -get-plugins=false
  ERROR and/or -plugin-dir on the command line.
  ...

With this commit, folks trying to 'create cluster' without libvirt
compiled in will get:

  FATAL failed to fetch Common Manifests: failed to load asset "Install Config": invalid "install-config.yaml" file: platform: Invalid value: types.Platform{AWS:(*aws.Platform)(nil), Libvirt:(*libvirt.Platform)(0xc4209511f0), OpenStack:(*openstack.Platform)(nil)}: platform must be one of: aws, openstack

before we get to Terraform.

Now that the build tag guards both creation and deletion, I've renamed
it from 'libvirt_destroy' to the unqualified 'libvirt'.

I've also adjusted the install-config validation testing to use
regular expressions so we can distinguish between failures because
libvirt was not compiled in as a valid platform and failures because
some portion of the libvirt configuration was broken.  In order to get
stable error messages for comparison, I've added some strings.Sort
calls for various allowed-value string-slice computations.
