In order to render configurable traffic profiles in NSB test cases,
a new variable is introduced: "extra_arg". The content of
this variable is added to the VNFD render data, under a key called
"extra_args".
This will allow the user to define Jinja templates for traffic profiles.
E.g.:
$ cat test_case_definition.yml
scenarios:
- type: NSPerf
traffic_profile: traffic_profile.yml
extra_args:
vports: 10
$ cat traffic_profile.yml
{% set vports = get(extra_args, 'vports', '0') or 4 %}
{% for vport in range(vports|int) %}
uplink_{{vport}}:
data...
{% endfor %}

"traffic_profile" modules should be imported only once. Every time
TrafficProfile.get is called, the modules under
"yardstick.network_services.traffic_profiles" are loaded [1]. Instead
of this, the modules should be registered only once the first time
"yardstick.network_services.traffic_profiles.base" is loaded. This
will reduce the execution time and will avoid unnecessary calls.

Add a new PortPair class to resolve the
topology into list of public and private ports.
Before we were calculating public/private in multiple
locations and using different conventions.
In addition for all the DPDK test we need to use the DPDK
port number and no rely on interface ordering or interface naming
conventions.
We used to use xe0 -> 0, xe1 -> 1, etc. This is not the DPDK port
number.
Use the new dpdknicbind_helper class to parse the output of
dpdk-devbind.py to find the actual DPDK port number at runtime.
We then use this DPDK port number to correctly calculate the
port_mask_hex.
The port mask maps the DPDK port num (PMD ID) to the LINK ID
used in the pipeline config
We also need to make sure we only use the interfaces matched to the
topology and not use all the interfaces, because in some cases we will
have unused interfaces. In particular TRex always requires an even
number of interfaces, so for single port TRex tests we have to create
the second port and not use it.
Thus we had to modify the traffic generator stats code to only dump
stats for used ports and no unused ports.
Ixia was using interface ordering to map to Ixia ports, instead we use
the dpdk_port_num which must be hardcoded for Ixia.
Renamed traffic_profile.execute to traffic_profile.execute_traffic so
we can trace the code easier.
We pass the port used by the traffic profile to generate_samples so we
don't get stats for unused ports.
Fixed up vPE config creation and bring up issues.
Fixed up CGNAPT and UDP_Replay to work correctly.
Tested with 4-port scale-out

This patch introduces the framework which is aligned with ETSI-TST001
This patch adds:
1. NetworkServiceTestCase introduces following functions
--> setup
--> Verify if infrastructure mapping can meet topology
--> Load VNF models
--> Fill traffic profile with information from topology
--> Provision VNFs
--> Run experiment (traffic)
--> run -> Yardstick calls run() at intervals defined in the yaml
and produces timestamped samples
--> teardown --> Stop VNFs
2. TrafficProfile is a generic class to get traffic profile for a given
testcase and select the traffic generator for testcase.
3. QueueFileWrapper is a class to send/recive cmds to vnf
4. GenericVNF is a generic class to instantiate VNF
5. GenericTrafficGen is a generic class to run/listen/verify traffic.
