Block non-accelerated data interface configuration with ovs-dpdk

[Ghada Khalil]

Brief Description
-----------------
ovs-dpdk does not support non-accelerated data interface configuration and fails silently. There is also partial code in stx-config (interface puppet manifest) which is related to non-accelerated data interfaces which needs to be removed.

This bug needs to remove the unsupported code as well as implement a semantic check to block this configuration.

Severity
--------
Minor

Steps to Reproduce

Attempt to configure a non-accelerated data interface using the system CLI cmd

Expected Behavior

Moving to stx.2019.03 as this is more of a preventative fix. Configuring a non-accelerated data interface is not a common configuration for starlingx

    Block the configuration of non-accelerated interface

    ovs-dpdk does not support non-accelerated data interface
    configuration and fails silently. There is also partial code
    in stx-config which is related to non-accelerated data
    interfaces which needs to be removed.

    This commit removes the unsupported code as well as implements
    a semantic check to block this configuration.
