[spp] [PATCH] spp-ctl: add APIs for pri for managing ports

[yasufum.o@gmail.com]

From: Yasufumi Ogawa <yasufum.o@gmail.com>

Add REST APIs for spp_primary for running `forward`, `stop` and
`patch` commands which are similar to spp_nfv. For example, forward
can be run with curl as below.

  $ curl -X PUT -H 'application/json' -d '{"action": "start"}' \
    http://127.0.0.1:7777/v1/primary/forward
