Three major changes to a generic RTE Flow API were implemented in order
to speed up flow rule insertion/destruction and adapt the API to the
needs of a datapath-focused flow rules management applications:
1. Pre-configuration hints.
Application may give us some hints on what type of resources are needed.
Introduce the configuration routine to prepare all the needed resources
inside a PMD/HW before any flow rules are created at the init stage.
2. Flow grouping using templates.
Use the knowledge about which flow rules are to be used in an application
and prepare item and action templates for them in advance. Group flow rules
with common patterns and actions together for better resource management.
3. Queue-based flow management.
Perform flow rule insertion/destruction asynchronously to spare the datapath
from blocking on RTE Flow API and allow it to continue with packet processing.
Enqueue flow rules operations and poll for the results later.
testpmd examples are part of the patch series. PMD changes will follow.

Since these are new APIs and won't impact existing code, I think
can be OK to get with -rc2, only concern may be testing.
@Andrew, can you please review this version too, if it is good
for you, we can proceed.
