Prior to this commit, providers like docker would fail to be brought up
because they do not store box objects like virtualbox or vmware
provider guests. This commit fixes that by making sure the box object
exists before writing the metadata file to disk.
When a guest is created, the box metadata information is stored in the
machine data directory. This allows modifications to happen to the
Vagrantfile definition of the box in use (box name change, box version
change, etc) while still allowing the Machine instance of an active
guest successfully load the box currently backing it.
Prior to this commit, when using a global id to bring up a vagrant vm,
vagrant would fail during the "install provider" step due to the fact
that the global vagrant machine was not configured for the local vagrant
environment. Since this global vm exists elsewhere, we disable the
install provider step so that vagrant can just bring up the global
vagrant machine.
