Artom Lifshitz 9ba07fdf9f Add tag column to vifs and bdm ...

This patch series adds the ability for a user to specify a tag to be
applied to a network interface or a disk when booting an instance.
This tag is then exposed through the metadata API. For example, a user
boots a VM with two network interfaces. One is connected to a private
network, the other to the public Internet. There is currently no
direct way to tell which interface is which. Specifying tags allows
the user to distinguish between the two interfaces.

This patch contains the database migration to add a 'tag' column to
the virtual_interfaces and block_device_mapping tables as well as the
corresponding change to the VirtualInterface and BlockDeviceMapping
objects.
