Create a role for OvS-DPDK host configuration

A new role has been created to initialize DPDK in
openvswitch. Currently, puppet-vswitch module does this
initialization. This role has the functionality in par
with current puppet-vswitch's dpdk implementation.
The goal is to remove the invocation of puppet-vswitch
in two places in THT by replacing it with this role.
