[spp] [PATCH v2 3/5] controller: change pri exit cmd to call REST API

[ogawa.yasufumi@lab.ntt.co.jp]

From: Yasufumi Ogawa <ogawa.yasufumi@lab.ntt.co.jp>

To send `exit` command to spp_primary, change to call REST API of
spp-ctl.

This patch includes update for removing `exit` from `pri` command
to avoid terminating spp_primary while running secondary processes.
Use `bye all` command for graceful terminating.
