[spp] [PATCH 2/2] spp-ctl: add port add and del APIs for spp_primary

[yasufum.o at gmail.com]

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

This update is to add REST APIs for adding ro deleting to spp_primary.
Here is an example for adding `vhost:1`.

    $ curl -X PUT -H 'application/json' -d \
      '{"action": "add", "port": "vhost:1"}' \
      http://127.0.0.1:7777/v1/primary/ports
