Merge pull request #1 from nsidc/master

Updating
Add the capability to configure the VLAN that the new clone will use.

This is very similar to the -cvlan capability that knife-vsphere gives you.

== DETAILS

-Added a new configuration option 'vlan' that lets you specify the vlan string
-If vlan is set, the clone spec is modified with an edit action to connect the first NIC on the VM to the configured VLAN.
