ifdown ethN before munging ifcfg-ethN

This is a patch for issue #1577 (reported by @chorankates-sfdc)

If vagrant munges `ifcfg-ethN` by removing the previous vagrant config for the interface before calling `ifdown`, all boxes after the first may encounter an ip address collision as noted [here](https://github.com/mitchellh/vagrant/pull/1577#issuecomment-26766758).  The simplest fix is to ensure that base boxes contain *NO* vagrant configured interfaces.  However, a more generic solution is simply to call `ifdown` before munging `ifcfg-ethN`.


## `Vagrantfile`
```
Vagrant.configure("2") do |config|
  config.vm.define :web do |web_config|
    web_config.vm.box = "rhel6_u2"
    web_config.vm.network "private_network", ip: "172.16.1.100"
    web_config.vm.provider :virtualbox do |vb|
      vb.customize ['modifyvm', :id, '--name', "web"]
    end
  end

  config.vm.define :db do |db_config|
    db_config.vm.box = "rhel6_u2"
    db_config.vm.network "private_network", ip: "172.16.1.101"
    db_config.vm.provider :virtualbox do |vb|
      vb.customize ['modifyvm', :id, '--name', "db"]
    end
  end
end
```

NOTE: I've intentionally left an `ifcfg-eth1` file in my base box.  It looks like this:
```
#VAGRANT-BEGIN
# The contents below are automatically generated by Vagrant. Do not modify.
BOOTPROTO=static
IPADDR=192.168.1.161
NETMASK=255.255.255.0
DEVICE=eth1
#VAGRANT-END
```

## Using commit [a92e03cf4ce936243d3959b7b5603262a234a58d](https://github.com/onejli/vagrant/commit/a92e03cf4ce936243d3959b7b5603262a234a58d)
As noted in my comments [here](https://github.com/mitchellh/vagrant/pull/1577#issuecomment-26278873) and [here](https://github.com/mitchellh/vagrant/pull/1577#issuecomment-26766758), the first box to the upped retains the ip address as specified by my stray `ifcfg-eth1` (even though an updated `ifcfg-eth1` has been pushed by vagrant).  The second box picks up the correct ip address as specified in the `Vagrantfile`.

You appear to be running Vagrant in a Bundler environment. Because
Vagrant should be run within installers (outside of Bundler), Vagrant
will assume that you're developing plugins and will change its behavior
in certain ways to better assist plugin development.

Vagrant should be run within installers (outside of Bundler), Vagrant
will assume that you're developing plugins and will change its behavior
in certain ways to better assist plugin development.

You appear to be running Vagrant in a Bundler environment. Because
Vagrant should be run within installers (outside of Bundler), Vagrant
will assume that you're developing plugins and will change its behavior
in certain ways to better assist plugin development.
