more concise message for BoxNotFound error

Now we have different providers, but the error message didn't tell
anything about it. Suppose I want to remove one of my boxes:

    vagrant box remove opscode-ubuntu-12.04 vritualbox

There is a typo in provider name. The error message is:

    Box 'opscode-ubuntu-12.04' could not be found.

Therefore I need to double check the box name, and only than I will see
the typo.

This commit make the error message looks like this:

    Box 'opscode-ubuntu-12.04' with 'vritualbox' provider could not be
found.
Import the TemplateRenderer (like the other guests do).
Changed Device name to fix private_network bug

If you try and start fedora with a :private_network, it will fail saying the 'p7p1 device doesn't exist'. Fixed with changing device to eth.
You need to include the module to use the class without ::s.

Vagrant reports properly error for not found command
DHCP renewal on Debian/Ubuntu after setting hostname

On Debian and Ubuntu guests, when the new hostname of the guest box is
set, the DHCP client (isc-dhcp-client) won't renew its DHCP lease with
the new hostname. Executing "ifdown -a; ifup -a" to reinitialize all auto
interfaces fixes this issue.

Furthermore, as vagrant will now actually wait until a DHCP lease is
acquired, it is guaranteed that the the correct domainname is set from
DHCP before calling other provisioners like puppet, that rely on it.
This fixes puppet/facter sometimes failing to find the fqdn fact on an
LXC guest when the DHCP server is responding too slow.
NFS exports with single quotes now work properly [GH-1166]
