With the introduction of inventory variables, group members provided as
String are not splitted (by ' ') into an array (instead of
auto-conversion to a single-item array).
String and Symbol types are different when used as a Hash key. By
default the Vagrant machine names are set in Symbol format, but users
may write their `host_vars` entries with String keys. This is a very
simple way to ensure smooth experience, without having to coerce the
data types during the config validation (e.g. with a library like
Hashie, which is currently not in the Vagrant dependencies)

This helps with some confusion caused in GH-2538, since the output says:
> Running cleanup tasks for 'shell' provisioner...
But that's actually not true. It is running the cleanup tasks iff the
provisioner defined a cleanup task. This commit changes the
provisioner_cleanup middleware to only run cleanup tasks if the subclass
defines a cleanup task.
The reason we can't just check if the provisioner `respond_to?` the
`cleanup` method is because the parent provisioner base class (which
all provisioners inherit from) defines a blank cleanup method. This is
important because it means we never risk calling an unimplemented
cleanup function, and it also helps define the public API for a
provisioner.
At the moment, the vagrant ssh username is used as default username when
force_remote_user option is disabled, even for winrm-communiating
machines. This could be improved in the future, but people hitting this
problem can easily work around it by syncing `config.ssh.unsername` and
`config.winrm.username` in their Vagrantfile.
ref #5086
This is required because the Chef Server almost always needs a node name to
interact. This will default to the hostname, but that's always going to be
`vagrant.vm`, which will collide easily.
This generates a random hostname with `vagrant-` as the prefix and stores the
result in the machine's data directory.
