Description of problem:
OVS-DPDK is mentioned as Tech Preview, and as now OVS-DPDK can be configured by TripleO, we didn't updated this documentation.
Let's just remove this documentation which is outdated.
The 'Configure DPDK for OpenStack Networking' guide has been removed for RHOSP 10.
An internal JIRA ticket has been raised to request the removal of the RHOSP 8 and RHOSP 9 versions of these guides across two languages (en and ja), and is in progress.
All versions of the guide have been removed from the documentation splash pages.
Moving this bug to CLOSED.
