In some cases with Generic FLow, it is only required to show the pattern
of spec and mask, but no need to add the flow. Therefore, add an option
in packetforge so that users can show spec and mask only.

Add a new tool packetforge to extras. This tool is to support generic flow.
Packetforge is a library to translate naming or json profile format flow
pattern to the required input of generic flow, i.e. spec and mask. Using
python script flow_create.py, it can add and enable a new flow rule for
an interface via flow VAPI, and can delete an existed flow rule as well.
Command examples are shown below. Json profile examples can be found in
./parsegraph/samples.
Naming format input:
python flow_create.py --add -p "mac()/ipv4(src=1.1.1.1,dst=2.2.2.2)/udp()"
-a "redirect-to-queue 3" -i 1
python flow_create.py --del -i 1 -I 0
Json profile format input:
python flow_create.py -f "./flow_rule_examples/mac_ipv4.json" -i 1
With this command, flow rule can be added or deleted, and the flow
entry can be listed with "show flow entry" command in VPP CLI.
Packetforge is based on a parsegraph. The parsegraph can be built by
users. A Spec can be found in ./parsegraph as guidance. More details
about packetforge are in README file.
