Ondrej Zajicek (work) 96e4d0960c Change 'graceful down' command to 'graceful restart' and update docs
The command initiating planned graceful restart including bird shutdown
should be called 'graceful restart' instead of 'graceful down', as the
later should be reserved for graceful shutdown in style of RFC 8326.
