Add support for tagged interfaces and require ovs module

Currently the module can't deploy VSM on a management interface
that is tagged. This commit adds support for these interfaces by
properly handling them from a puppet perspective. Additionally
rather than calling similar code to check if OVS exists we call
the OVS module directly.
