[spp] [PATCH 1/5] controller: change name of plugins directory

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

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

Refactor directory name of command plugins from 'command' to 'plugins'
because commands of not plugin are moved to 'commands' directory and
the name of plugins is ambiguous from 'command'.
