Move all example boxes in a common directory

+# Vagrant LXD Example Boxe
+
+## Vagrant box format
+
+Vagrant providers each require a custom provider-specific box format.
+Here are some examples of boxes for the `lxd` provider.
+
+## The `lxd` box format
+
+The `lxd` provider right now just uses the default lxd images provided
+by the lxd images: remote. Upon start these will be provisioned with an
+vagrant ssh user and the unsafe common pubkey of vagrant and
+sshd will be enabled. All the necessary commands are defined in the
+metadata.json file.
+
+## Bootstraped provisioners
+
+The boxes here are prepared to run with the ansible provisioner.
