This allows Vagrant to calculate if a container's arguments (such as the run
arguments) have changed in the Vagrantfile since the original run.
Fixes GH-3055
When provisioning multiple machines in sequence (the default vagrant
behaviour), it doesn't make sense to require to provide the private ssh
key(s) via the custom ansible inventory script/file.
To align with the handling of multiple ssh keys per machine, we won't
rely any longer on `--private-key` command line argument, but only pass
the keys via `ANSIBLE_SSH_ARGS` environment variable.
Note that when vagrant generates the ansible inventory and that only one
key is associated to a VM, this step would be redundant, and therefore
won't be applied.
This change fixes the breaking change introduced by 3d62a91.
Vagrant 1.7.1 creates and injects new ssh keys for each virtual machine.
When it started ansible with the "parallel provisioning trick",
it would only send the ssh key of the targeted virtual machine.
With this change, vagrant now stores the ssh key for each virtual
machines directly in the generated ansible inventory, and thus allow
ansible parallelism.
Note that this change is not sufficient, as it would break vagrant
configuration based on a custom inventory (file or script). This issue
will be addressed in a next commit.

The Ansible Vagrant provisioner has a race where the inventory file is
updated every time the provisioner runs unless a file is provided.
Therefore if Ansible attempts to provision two nodes in parallel, you
may see the following race:
* System A writes the inventory file and calls Ansible.
* System B starts to provision and truncates the file before
creating a new one.
* Ansible on system A now attempts to read the inventory
file, which is blank. Ansible bombs out with "ERROR: provided
hosts list is empty".
To fix this, we only allow Vagrant to update the inventory file if
it needs to.
Revert 1c884fa4e5 which introduced the
following bug:
Instead of allowing to dump the `ansible-playbook` command details when
VAGRANT_LOG=debug was defined, it was then impossible to disable this
console output when VAGRANT_LOG was undefined (in such case,
``@logger.debug? systematically returns `true`)
In order to keep things simple and focused, it is preferable to drop the
bad idea to mix Ansible verbosity and Vagrant log level.
