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.
This patch introduces a new parameter --all for the remove
command of the box plugin. Setting this parameter will remove
all available versions of a specific box.
Example usage:
```
$ vagrant box list
ubuntu/trusty64 (virtualbox, 20150427.0.0)
ubuntu/trusty64 (virtualbox, 20150430.0.0)
ubuntu/trusty64 (virtualbox, 20150506.0.0)
```
```
$ vagrant box remove ubuntu/trusty64
You requested to remove the box 'ubuntu/trusty64' with provider
'virtualbox'. This box has multiple versions. You must
explicitly specify which version you want to remove with
the `--box-version` flag. The available versions for this
box are:
* 20150427.0.0
* 20150430.0.0
* 20150506.0.0
```
With the --all parameter it is possible to remove all versions at once.
```
$ vagrant box remove --all ubuntu/trusty64
Removing box 'ubuntu/trusty64' (v20150506.0.0) with provider 'virtualbox'...
Removing box 'ubuntu/trusty64' (v20150430.0.0) with provider 'virtualbox'...
Removing box 'ubuntu/trusty64' (v20150427.0.0) with provider 'virtualbox'...
```
With this change, the existing host-based Ansible provisioner is
refactored to share a maximum of code with this new guest-based Ansible
provisioner.
At this stage of development, the existing unit tests are intentionally
modified as little as possible, to keep safe the existing funtionalities.
Other issues resolved by this changeset:
- Display a warning when running from a Windows host [GH-5292]
- Do not run `ansible-playbook` in verbose mode when the `verbose` option
is set to an empty string.
